Abstract:
Electromagnetic simulation packages for nanoparticles have become of interest for science and engineering community because of interesting properties of nanomaterials, such as, plasmonics and localized field enhancement. There are several approaches to calculate electromagnetic wave responses including time domain and frequency domain; each approach does have its own pros and cons. In this paper, we discuss basic principle of Rigorous coupled wave analysis (RCWA) and some key issues of 2D Rigorous Coupled Wave Analysis (RCWA) for nanoparticle simulation, such as, the computing demands (long computation time and memory consumption) and staircase approximation. We also suggest some feasible approaches to get around the issues and speed up the calculation, such as, employing Li Feng Li’s RCWA algorithm for circular and elliptical rods, making use of the symmetry of spherical shape particles to reduce redundancies in computation and building up an Eigenvector/Eigenvalue database of difference radii of disks, so that these disks can be stacked together to form various sizes of nanospheres.

Design and analysis of complex nanophotonic and nanoelectronic structures require significant computing resources. Cloud computing infrastructure allows distributed parallel applications to achieve greater scalability and fault tolerance. The problems of effective use of high-performance computing systems for modeling and simulation of subwavelength diffraction gratings are considered. Rigorous coupled-wave analysis (RCWA) is adapted to cloud computing environment. In order to accomplish this, data flow of the RCWA is analyzed and CPU-intensive operations are converted to data-intensive operations.

Abstract:
Since the development almost a decade ago of the first biosensor based on surface plasmon resonance (SPR), the use of this technique has increased steadily. In this study, we theoretically investigated the sensing character of SPR sensor with reflection type metallic with Rigorous Coupled Wave Analysis (RCWA) method, and the mechanism is analyzed by the field distribution. It is found that the sensitivity of negative diffraction order, which goes higher quickly as the resonant angle increases, is much greater than that of positive diffraction order.

Abstract:
AbstractIn this paper, we present a rigorous coupled-wave analysis (RCWA) of absorption enhancement in all-silicon (Si) photodiodes with integrated hole arrays of different shapes and dimensions. The RCWA method is used to analyze the light propagation and trapping in the photodiodes on both Si-on-insulator (SOI) and bulk Si substrates for the datacom wavelength at about 850 nm. Our calculation and measurement results show that funnel-shaped holes with tapered sidewalls lead to low back-reflection. A beam of light undergoes a deflection subsequent to the diffraction in the hole array and generates laterally propagating waves. SOI substrates with oxide layers play an important role in reducing the transmission loss, especially for deflected light with higher-order diffraction from the hole array. Owing to laterally propagating modes and back-reflection on the SiO2 film, light is more confined in the thin Si layer on the SOI substrates compared to that on the bulk Si substrates. Experimental results based on fabricated devices support the predictions of the RCWA. Devices are designed with a 2-μm-thick intrinsic layer, which ensures ultrafast impulse response (full-width at half-maximum) of 30 ps. Measurements for integrated photodiodes with funnel-shaped holes indicate an enhanced external quantum efficiency of more than 55% on the SOI substrates. This represents more than 500% improvement compared to photodiodes without integrated phototrapping nanoholes.

This paper presents the simulation results of top nano-grating on solar cell using rigorous coupled wave analysis (RCWA) method. However, compared to other simulation results, we calculated weighted total transmission of solar cell according to Sun spectrum and Silicon photo detector responsivity. Our optimization shows that the top grating with period 200nm, width 40nm, and height 150nm is the optimization structure. This case has 0.45544 total weighted transmission powers and is about 70.9% improvement compared to the non-grating case.

Abstract:
A variety of light management structures have been introduced in solar cells to improve light harvesting and further boost their conversion efficiency. Reliable and accurate simulation tools are required to design and optimize the individual structures and complete devices. In the first part of this paper, we analyze the performance of rigorous coupled-wave analysis (RCWA) for accurate three-dimensional optical simulation of solar cells, in particular heterojunction silicon (HJ Si) solar cells. The structure of HJ Si solar cells consists of thin and thick layers, and additionally, micro- and nano-textures are also introduced to further exploit the potential of light trapping. The RCWA was tested on the front substructure of the solar cell, including the texture, thin passivation and contact layers. Inverted pyramidal textures of different sizes were included in the simulations. The simulations rapidly converge as long as the textures are small (in the (sub)micrometer range), while for larger microscale textures (feature sizes of a few micrometers), this is not the case. Small textures were optimized to decrease the reflectance, and consequently, increase the absorption in the active layers of the solar cell. Decreasing the flat parts of the texture was shown to improve performance. For simulations of structures with microtextures, and for simulations of complete HJ Si cells, we propose a coupled modeling approach (CMA), where the RCWA is coupled with raytracing and the transfer matrix method. By means of CMA and nanotexture optimization, we show the possible benefits of nanotextures at the front interface of HJ Si solar cells, demonstrating a 13.4% improvement in the short-circuit current density with respect to the flat cell and 1.4% with respect to the cell with double-sided random micropyramids. We additionally demonstrate the ability to simulate a combination of nano- and microtextures at a single interface, although the considered structure did not show an improvement over the pyramidal textures.

Abstract:
Two-dimensional arrays of hollow nanotubes made of TiO 2 are a promising platform for sensing, spectroscopy and light harvesting applications. Their straightforward fabrication via electrochemical anodization, growing nanotube pillars of finite length from a Ti foil, allows precise tailoring of geometry and, thus, material properties. We theoretically investigate these photonic crystal structures with respect to reduction of front surface reflection, achievable field enhancement, and photonic bands. Employing the Rigorous Coupled Wave Analysis (RCWA), we study the optical response of photonic crystals made of thin-walled nanotubes relative to their bare Ti foil substrate, including under additional charge carrier doping which might occur during the growth process.

This paper designed a novel three-output reflective packaged grating. The optimized parameters such as the period and depth of the high-efficiency three-output grating with an incident wavelength of 1550 nm can be calculated by rigorous coupled-wave analysis (RCWA). According to the optimized result, the grating can diffract the incident light energy into three orders with an efficiency of nearly 33% under the premise of second Bragg angle incidence and the given duty ratio of 0.5. The diffraction efficiency of the packaged grating is improved compared to the surface-relief three-output grating under second Bragg angle incidence, especially for TE-polarized light.

Abstract:
Tailoring the radiative properties of periodic micro/nanostructures can be used as an efficient way to create devices which have applications in energy harvesting, bioengineering and optical sensing. These structures are analyzed by a rigorous solution of the electromagnetic wave phenomena at the interfaces. The thesis explores the application of rigorous coupled-wave analysis (RCWA) method to study the optical responses of microstructure arrays. First section of the thesis elucidates the various mechanisms which are responsible for causing enhanced light absorption in inclined parallel plate grating arrays. Illustrative evidences of surface plasmon and magnetic resonances are provided by one and two-dimensional plots prepared by RCWA. Analytical agreement with visual data is obtained through use of LC circuit models. Finally, the effects of different geometric parameters on the resonance conditions are investigated. The second part of the thesis deals with application of RCWA to study the effect of light scattering on inclined silver nanorod (AgNR) arrays grown on compact disc (CD) gratings. Depending on the manner in which AgNRs are oriented with respect to CD gratings, they exhibit different optical behavior to incoming light. Effects of both incident light polarization and AgNR orientation with respect to the grating have been studied through the use of RCWA and effective medium theory. Calculated results are compared with experimental values and good agreements are observed for total reflection as well as trends of individual diffraction orders.

Abstract:
We propose in this work a structure of semiconductor thin films combined with a one-dimensional metallic grating which allows for selective improvement of thermal radiative absorptivity (also emissivity) of the structure. We numerically demonstrate with a 2-D rigorous coupled-wave analysis (RCWA) algorithm that the proposed structure exhibits enhanced spectral absorptivity (for p-polarization) for photon energy slightly above the gap energy of the semiconductor (silicon in this work). The enhanced absorptivity is explained as due to excitations of surface polaritons (SPs) in the grating region, along with interactions of multiple-order diffracted waves in the semiconductor layer. Furthermore, the enhanced absorptivity of the structure can be achieved for a wide range of incidence angles so that it may have potential applications in energy conversion purposes.

Abstract:
The optical performance of four lattice crystalline silicon nanostructures, i.e., cylinder nanowire arrays, cylinder nanohole arrays, square nanowire arrays and square nanohole arrays is numerically investigated in this paper. The method of rigorous coupled-wave analysis (RCWA), an efficient and accurate computational tool, is used to calculate the optical absorption for the lattice constant from 100 nm to 1500 nm. The results indicate that the lattice constant is the foremost structure parameter to determine the ultimate efficiency, and the ultimate efficiencies are reached at the lattice constant around 600 nm. The optimal filling ratio of square nanowire arrays is the lowest among the four nonostructures, whereas the cylinder nanohole arrays exhibit a broad range of optimal filling ratios. Lower optimal filling ratios implies that the nanostructures cost less raw material while maintain the high ultimate efficiencies. The high ultimate efficiency of all structures can be achieved over a large range of incident angles, even the efficiency will slowly decrease as the incident angle increases.

Abstract:
Temperature nonuniformity is a critical problem in rapid thermal processing (RTP) of wafers because it leads to uneven diffusion of implanted dopants and introduces thermal stress that can produce defects. One cause of the problem is nonuniform absorption of thermal radiation, especially in patterned wafers, where the optical properties vary across the surface of the wafer. Recent developments in RTP have lead to the use of millisecond-duration heating cycles, where light with very high power density is used to heat the surface of the wafer. Pattern effects are especially important here, because there is very little time for thermal diffusion to even out temperature distributions during the heating cycle. There have been very few studies on the radiative properties of patterned wafers, especially for the structures expected to be used on advanced semiconductor devices. The feature size is already below 100 nm and is comparable or smaller than the wavelengths of radiation (200–1000 nm) emitted by the flash-lamps typically used for millisecond processing. Hence, this work is devoted to a parametric numerical study of the radiative properties of patterned wafers with the smallest dimension down to 30 nm. The effects of wavelength, wave polarization, and angle of incidence on selected periodically patterned wafers are presented. The methods include the rigorous coupled wave analysis (RCWA) and the effective medium approach (EMA). RCWA is used to obtain exact solutions of Maxwell’s equations, and EMA is used to approximate the periodic structures as a planar multilayer structure with an effective dielectric function. This study provides an assessment of the applicability of EMA for simulations of radiative properties of patterned wafers.

Abstract:
At present, the utilization of thermal energy from sunlight has been widely adopted as the working principle of concentrated solar power (CSP) generation systems. In this research, we suggest a CSP technology based on the properties of transparent conductive oxide (TCO) thin films on metal substrates which is compatible with mass production of solar selective absorbers that can be utilized at high temperatures. Since the plasma wavelength of TCO materials is in the infrared region, electromagnetic waves with wavelengths longer than the plasma wavelength are reflected at the surface, whereas electromagnetic waves with shorter wavelengths pass through the surface layer and reach the substrate. In other words, a TCO thin film behaves as an antireflection film only in the transparency range of TCO coating. This phenomenon is demonstrated through numerical simulations based on rigorous coupled-wave analysis (RCWA). The prepared samples also show favorable spectral selectivity and satisfactory performance as solar selective absorbers, with a solar absorptance of 0.76, a thermal emittance of 0.12 at 800°C and a spectral selectivity of 6.5 at 800°C.

Abstract:
The sunlight has been considered a promising alternative energy source because of its abundance and sustainability. A solar thermal collector can turn the solar irradiation into the usable heat, and thus, its performance highly depends on the efficiency of absorber. An ideal absorber should trap most incoming solar radiation in the visible and near-infrared spectral region, and minimize its emitted thermal energy at long wavelengths. One of the promising solutions for satisfying the aforementioned requirements is to employ periodic structured surfaces, whose tunable radiative properties were used in thermophotovoltaic devices and chemical sensors. Two-dimensional subwavelength gratings are thus proposed for the absorber surface profile in the present study. Design objectives are a broad-band peak in the absorption spectrum and a quasi-isotropic angular lobe at the incidence of both linear polarizations. Nickel is selected for its fabrication easiness and low cost. A SiO2 film sandwiched between gratings and a substrate is considered as extra design flexibility to possibly enhance performance without much difficulty. Radiative properties and electromagnetic fields will be obtained from programs based on the rigorous coupled-wave analysis (RCWA). The optimization is then realized with the Taguchi method.

Abstract:
The wavelength-selective radiative properties are becoming noticeable requirements in various technological fields. There have been many researches focus on the radiative properties of periodic microstructured surface of metals. However, the spectral bandwidth of high absorptance is often too narrow by applying the conventional grating structures. In order to solve this problem, in this paper we propose two novel periodic grating structures, which can widen the spectral bandwidth of high absorptance. One of the new periodic grating structures, called dual-groove grating, is constructed by adding a rectangular groove at the bottom of the simple binary grating’s groove through a secondary microscale processing. The other novel grating structure, which is called complex dual-groove grating, is constructed by superposing a dual-groove grating and a simple binary grating within one period. Aluminum grating structure is taken as an example to show how the geometric parameters based on the novel structure widen the spectral bandwidth of high absorptance within mid-infrared and far-infrared spectra. The rigorous coupled-wave analysis (RCWA) is used to calculate the absorptance of periodic grating structures. The results show that, two close absorption peaks and three connecting absorption peaks are obtained respectively for the two novel periodic grating structures. These two novel structures may widen the effective spectral bandwidth of high absorptance of the microscale periodic grating structures.
