Abstract:
Mode-locking refers to the generation of ultrashort optical pulses in laser systems. A comprehensive study of achieving high-energy pulses in a ring cavity fiber laser that is passively mode-locked by a series of waveplates and a polarizer is presented in this paper. Specifically, it is shown that the multipulsing instability can be circumvented in favor of bifurcating to higher-energy single pulses by appropriately adjusting the group velocity dispersion in the fiber and the waveplate/polarizer settings in the saturable absorber. The findings may be used as practical guidelines for designing high-power lasers since the theoretical model relates directly to the experimental settings.

Abstract:
In this work, we investigate a thin-film polarizer for a high intensity of the electromagnetic (EM) beam based on Cr nano wire arrays. Commonly used thin-film polarizing components are very sensitive for high power of EM waves and can be easily damaged by focused beams. The solution to this problem could be the thin-film polarizer based on metallic subwavelengths structures. This type of optical element has huge resistance comparing to typical thin-film polarizers. However, designing such an optical element for proper wavelength of EM wave and transmissions is not easy task. In this paper we present numerical as well as experimental results for specially designed chromium thin-film polarizer for wavelength 532nm Full Text: PDF ReferencesW. Zhou, K. Li, C. Song, P.

Abstract:
MARIA (magnetism reflectometer with high incident angle) is a world class vertical sample reflectometer dedicated to the investigation of thin films in the fields of magnetism, soft matter and biology. The elliptical vertically focusing guide allows one to measure small samples with a typical size of 1 × 1 cm very efficiently. The double-bounce polarizer and the in situ pumped 3He SEOP (spin-exchange optical pumping) neutron spin filter cell for analysing the polarization of the reflected neutron beam can be moved into the beam in seconds. The polarized flux of MARIA amounts to 5 × 107 n (s cm2)−1 at the sample position with a horizontally collimated beam of 3 mrad, a wavelength of λ = 4.5 Å and a wavelength resolution of Δλ/λ = 10%. In the non-polarized mode a flux of 1.2 × 108 n (s cm2)−1 is achieved in this configuration. MARIA is also capable of grazing-incidence small-angle neutron scattering measurements, using a pinhole collimation with two four-segment slits and an absorber that prevents the focusing of the elliptical guide in the vertical direction.

Abstract:
A Jaumann absorber with its metal backing replaced with a combined low-pass and polarizer FSS is investigated with respect to its absorption and its polarization-dependent low-frequency transparency properties. This structure is applied to an idealized curved wing-front end, and its monostatic radar cross-section is determined. The FSS-Jaumann structure preserves an absorption similar to the planar Jaumann absorber in the higher frequency interval and enables a partial transparency in the TEzpolarization at 1 GHz. In addition, once the structure is applied to the wing-front end, a significant reduction in two-dimensional radar cross-section for both the TMzand TEzpolarization over 2–16 GHz is observed. A sensitivity analysis shows that the resistivity of the inner resistive layer has a large impact on the 1 GHz transmission.

Abstract:
Infrared polarization imaging holds significant promise for enhancing target recognition in both civil and defense applications. The Division of Focal Plane (DoFP) scheme has emerged as a leading technology in the field of infrared polarization imaging due to its compact design and absence of moving parts. However, traditional DoFP solutions primarily rely on micro-polarizer arrays, necessitating precise alignment with the focal plane array and leading to challenges in alignment and the introduction of optical crosstalk. Recent research has sought to augment the performance of infrared detectors and enable polarization and spectral selection by integrating metamaterial absorbers with the pixels of the detector. Nevertheless, the results reported so far exhibit shortcomings, including low polarization absorption rates and inadequate polarization extinction ratios. Furthermore, there is a need for a comprehensive figure of merit to systematically assess the performance of polarization-selective thermal detectors. In this study, we employ the particle swarm optimization algorithm to present a multilayer, multi-sized metamaterial absorber capable of achieving a remarkable polarization-selective absorption rate of up to 87.2% across the 8–14 μm spectral range. Moreover, we attain a polarization extinction ratio of 38.51. To elucidate and predict the resonant wavelengths of the structure, we propose a modified equivalent circuit model. Our analysis employs optical impedance matching to unveil the underlying mechanisms responsible for the high absorption. We also introduce a comprehensive figure of merit to assess the efficacy of infrared polarization detection through the integration of metamaterials with microbolometers. Finally, drawing on the proposed figure of merit, we suggest future directions for improving integrated metamaterial absorber designs, with the potential to advance practical mid-infrared polarization imaging technologies.

Abstract:
Spin polarized metastable deexcitation spectroscopy provides an important surface probe, in which a beam of thermal energy metastable noble gas atoms is deexcited at the target surface under study, releasing its energy through ejection of electrons. The electrons are collected and their energy distributions measured to reveal the surface electronic structure. By spin polarizing the incoming metastable atoms and measuring the polarization of the ejected electrons, additional insight into the reaction mechanisms can be obtained. In the investigation reported in this thesis, polarized He(2$\sp3$S) atoms are used to probe a thin film of gases frozen on a cooled Cu(100) surface. The experimental results show that the reaction mechanisms occurring are similar to gas phase Penning Ionization, although some differences are apparent that can be attributed to interaction with neighboring particles and to the presence of the substrate metal surface.

Abstract:
Abstract Proteins absorb light and emit radiation in the UV range of the spectrum. The absorbance is caused by the peptide groups, by the aromatic amino acids, and to a small extent, by disulfide bonds. Fluorescence emission originates from the aromatic amino acids. Some proteins that carry covalently linked cofactors, such as the haem proteins, also show absorbance in the visible range. Proteins also absorb infrared light. The latter two properties will not be dealt with in this chapter. During absorption, light energy is used to promote electrons from the ground state to an excited state. Electrons that participate in delocalized aromatic systems frequently absorb in the near-UV or the visible region. Fluorescence emission is observed when excited electrons revert from the first excited state to the ground state. When a chromophore is part of an asymmetric structure, or when it is immobilized within an asymmetric environment, left-handed and right-handed circularly-polarized light is absorbed to different extents. This phenomenon is called circular dichroism (CD).

Abstract:
Abstract Dichroism is the polarization dependence of the absorption of light. In general, the response of an electron charge distribution to an electromagnetic disturbance is anisotropic, due for example to the directionality of chemical bonds, crystal fields, and molecular orientation. Depending on the local symmetries exhibited by a material, this can lead to linear- and/or circular-polarization-dependent attenuation coefficients. Undoubtedly, the most famous example of linear dichroism at optical wavelengths is Polaroid sheet, in which oriented long-chain molecules absorb only the component of light which is linearly polarized parallel to the chains. Dichroism has been observed in a wide range of materials, at wavelengths extending up to hard X-rays. In the X-ray region, though, the effect is usually only significant very close to absorption edge resonances, where the excited photoelectrons are most strongly influenced by the internal fields of the absorber.

Abstract:
Abstract The absorption spectrum of a solution of chiral molecules measured with left circularly polarized radiation would differ by at the very most 2% from that measured with unpolarized or right circularly polarized light. For most samples the difference between the absorbances measured with left and right circularly polarized light rarely exceeds ±0.001%. A CD spectrum is thus the result of a small difference between two large absorbance numbers. It gives only the helical or asymmetric part of the change that occurs when radiation is absorbed and this is probed by a combination of the electric and magnetic fields of the radiation. The smallness of the difference is due to the fact that at a given field strength magnetic field interaction energies are some thousand times weaker than the corresponding electric field interaction energies.

Abstract:
In this chapter, the production of carbon nanotube (CNT)-cellulose composite sheets and their electrical conductivity have been studied. Good electroconductive CNT-cellulose composite sheets and good electromagnetic interference (EMI) shields have been obtained. Single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) were used to produce the CNT-cellulose composite sheets. In the ecofriendly process, CNTs, cellulose, and gelatin were mixed well to prepare the sheets. The performance of the SWCNTs-cellulose and MWCNTs-cellulose composite sheets was studied for 8.9, 13, and 17 wt% of CNT contents. Their electrical properties were measured by the DC current method, and their optical properties (reflection and absorption) were measured using a microwave transmitter of 10.5 GHz. Herein, significant differences in the electric properties and the EMI shielding effects between the MWCNTs-cellulose and the SWCNTs-cellulose composite sheets were found. The SWCNTs-cellulose composite sheets showed good characteristics for electromagnetic wave (EMW) shielding. In the microwave region, the SWCNTs-cellulose composite sheets showed lower transmission and higher reflection properties compared to the MWCNTs-cellulose composite sheets. The shields do not generate dust or particles and possess flexibility and toughness. With these sheets, 3D flexible circuits, flexible electric heaters, EMW shields, EMW polarizers, and cone-shaped EMW absorbers could be prepared.

Abstract:
Circular dichroism (CD) is the ideal technique for studying chiral molecules in solution. It is uniquely sensitive to the asymmetry of the system. These features make it particularly attractive for biological systems. CD is by definition the difference in absorption, A, of left and right circularly polarized light (CPL): . . . CD = Ae − Ar . . . . . . 1 . . . CPL has the electric field vector of the electromagnetic radiation retaining constant magnitude in time but tracing out a helix about the propagation direction. Following the optics convention we take the tip of the electric field vector of right CPL to trace out a right-handed helix in space at any instant of time (1, 2). CD spectra can in principle be measured with any frequency of electromagnetic radiation. In practice, most CD spectroscopy involves the ultraviolet-visible (UV-visible) regions of the spectrum and electronic transitions, though increasing progress is being made with measuring the CD spectra of vibrational transitions using infrared radiation. We shall limit our consideration to electronic CD spectroscopy since the practical considerations for vibrational CD differ from those for electronic CD. For randomly oriented samples, such as solutions, a net CD signal will only be observed for chiral molecules (ones that cannot be superposed on their mirror images (3)). Oriented samples of achiral molecules, such as crystals, will also give a CD spectrum unless the optical axis of the sample aligns with the propagation direction of the radiation. However, such spectra are seldom useful. CD is now a routine tool in many laboratories. The most common applications include proving that a chiral molecule has indeed been synthesized or resolved into pure enantiomers and probing the structure of biological macromolecules, in particular determining the α-helical content of proteins. Figure 3 gives an example of a CD spectrum. The key points to remember are that a CD signal is observed only at wavelengths where the sample absorbs radiation, i.e. under absorption bands, and the signal may be positive or negative depending on the handedness of the molecules in the sample and the transition being studied.

Abstract:
Metamaterials have been realized for exotic optical phenomena which can not be found in nature, such as negative refractive index and cloaking. Nowadays, people intend to be more precisely from fundamental physical response to specific functionalities in metamaterials on demand for the development on practical applications, such as optical switches, phase gradient surfaces[1,2], optical modulators, polarizer and wave plate. One of the potential applications is the metamaterial based perfect absorber (MPA)[3]. Due to the strong electromagnetic field confinement arising from surface plasmon resonance, MPA provides a benefitting way for enhancing the efficiency in solar energy capture, nanoplasmonic sensor and bolometer. The commonly utilized structural configuration for MPAs is incorporating a metamaterial array with a perfect reflective mirror separated by a dielectric spacer. Because of the near-field interaction between metamaterials and its mirror images, a strong plasmon field confinement is involved and therefore dramatically enhances the absorption intensity. However, both the electric and magnetic responses play an important role to those of electromagnetic media, especially for the nonlinearity responses. Vertical split-ring resonator (VSRR) attracts a wide interest because it found out that the magnetic reciprocal coupling of incident light [4,5].

Abstract:
In a LCTV-VIDIC system, infrared plane polarizers are really needed. Because of the high technology precision and price of wired-grid polarizers, we have hoped to obtain infrared plane polarizers as we have in the visible region. In our experiments, we obtained them by field controlling homogeneously aligned LC (Δε > 0); molecular realignment to tended to be parallel with the direction of the field and the incident unpolarized light. The conditions for realizing n-LC infrared plane polarizers are an infrared n-LC (Δε > 0 for us), an infrared film electrode, and a controlling field. There are two kinds of these polarizers: a direct field controlling n-LC to realign (V=2 v, T=100 ms, P=85%) and field controlling polymer dispersed n- LC (V=30 v, T=40 ms, P=80%). The properties (V, t) are the same as in a display. V and Δε are important factors of P (P increases with V). The polarizer is not ideal in P and lifetime, but it is satisfactory for simulation experiments. Its mechanism is that liquid crystal molecules' absorbtion is different for the two lights of bifraction. One direction of field vibrational energy is heavily absorbed, while the other is hardly absorbed at all. This device's advantages are IR operation, a large plane parallel to incident light, and an infrared plane LC modulator. Therefore it is very convenient in an LCTV-VIDIC system.
