Abstract (sommario):
Abstract Shaping the emission pattern of second harmonic (SH) generation from plasmonic nanoparticles is important for practical applications in nonlinear nanophotonics but is rendered challenging by the complex second-order nonlinear-optical processes. Here, we theoretically and experimentally demonstrate that a pair of V- and Y-shaped gold nanoparticles directs the SH emission perpendicularly to an incident light direction. Owing to spatial overlap of two orthogonal plasmonic dipole modes at the fundamental and SH wavelengths of the individual particles, surface SH polarizations induced by the fundamental field is efficiently near-field coupled to the SH plasmon mode, resulting in dipolar SH emission from the individual particles. Moreover, the phase of this emission can be tuned simply by altering the part of the Y-particle shape, which changes the SH plasmon resonance while keeping the fundamental resonance. Our approach is a promising platform for engineering not only directional nonlinear nanoantennas but also nonlinear metamaterials.

Abstract (sommario):
A nanoantenna with Fano response is designed with plasmonic oligomers as a refractive index sensor to enhance surface-enhanced Raman scattering (SERS) in the visible light spectrum. The scattered radiation and field-enhanced interactions of the outer gallium phosphide (GaP) nanoring assembled with an inner heptamer of silver with Fano response are investigated systematically using the finite element method. The characteristics of Fano resonance are found to depend on the size, shape and nature of the materials in the hybrid nanoantenna. The confined electromagnetic field produces a single-point electromagnetic hotspot with up to 159.59 V/m. The sensitivity obtained from the wavelength shift and variation in the scattering cross-section (SCS) shows a maximum value of 550 nm/RIU. The results validate the design concept and demonstrate near-field enhancement, enabling the design of high-performance nanoantennas with enhanced optical sensing and SERS properties.

Abstract (sommario):
The thermal distribution in the diseased tissue treated by different methods faces the problem of an uncontrollable defused heat. In the present article, we use a plasmonic bowtie nanoantenna working in the near infrared region to enhance the temperature confinement in the tissue. The Computer Simulation Technology Studio Suite package version 2019 was used to execute the design of both plasmonic nanoantenna and the tissue. Gold nanostructure and silicon carbide dioxide are the components the plasmonic nanoantenna in the bowtie shape. The results showed that the distance between the tumor tissue and the antenna is important to determine the intensity field where the maximum field is 5.9*107 V/m at a distance of 100 nm. The maximum specific absorption rate is 1.92*1011 W/kg at a similar distance which gives a higher temperature in the tissue of 580 Co. It is concluded that from the obtained results that the near infrared (1064 nm) resonance wavelength is recommended in the treatment of cancer cell by plasmonic bowtie nanoantenna because higher intensity field is generated. The closer distance to the nanoantenna gives higher temperature in the tissue while the temperature gradually decreases in the tissue till 400 nm where no valuable temperature was detected.

Abstract (sommario):
To convert the energy of free propagating radiation to localized energy and localized energy into free propagating radiation energy, we have always been reliant on radio wave and microwave antennas. But with the developments in physical optics, optical antennas are garnering attraction. Properties of metal nanostructures which behave as strongly coupled plasmas at optical frequencies forms the basis for the operation of optical antennas. Optical antennas can overcome the limitations of light-emitting devices, photovoltaics and spectroscopy by increasing the light-matter interaction. Televisions, cell-phones and other communication equipment which work on electromagnetic antennas, mostly use radio-wave or microwave ambit of the electromagnetic spectrum. Contrary to the electromagnetic fields, optical frequencies are controlled by re-directing the wave fronts of propagating radiation by means of lenses, mirrors, and diffractive elements. There are several current studies which have been undertaken to find ways of translating established radio wave and microwave antenna theories into the optical frequency regime and with few successes attained with the help pf nano-optics and plasmonics, optical antennas may soon be a thing of practical use. Once we are able to extend the concept of antennas into optical frequency regime, we can have major technological advancements ranging from enhanced absorption cross-sections and quantum yields in photovoltaics, releasing energy efficiently from nanoscale lightemitting devices, boosting the efficiency of photochemical or photophysical detectors, to improving spatial resolution in optical microscopy.
