In this paper, soliton pulse generation and collision in chalcogenide As2Se3 glass Photonic Crystal Fiber (PCF) is
numerically studied using our own algorithm developed for
Fourth-Order Runge-Kutta in the Interaction Picture
(RK4IP) method. The numerically obtained value of soliton collision length is found to be in good agreement with the
theoretical value obtained by the inverse scattering transform, thus providing a verification of the accuracy of the method
in solving Generalized Nonlinear Schrödinger Equation (GNLSE). We also calculate the value of wavelength for least
distortion for soliton optical pulses.
Dispersion and resonance properties of double nanorod structure, ring structure, H structure and chair type structure is
demonstrated. With some structural modification, the properties of the structure changes from isotropic to uni-axial
anisotropic and further to chiral left-handed material. The Demonstration of near-field transmission spectrum reveals the
production of the local-field enhancement up to 102 for the green light. Negative real values of both permeability (μ) and
permittivity (ε) for visible light are obtained by applying coupled dipole approximation. The structure modification
exhibits some unique dispersion and resonant properties that may govern imaging applications.
A left-handed plasmonic optical nanoantenna is presented to demonstrate blue light generation with the
incident red light through second harmonic generation. Negative real values of permeability and permittivity with
extremely low imaginary values for visible light is obtained by applying coupled dipole approximation. Near-field and
far-field resonance spectrums reveal high directionality for the designed nano-antenna.
A new design of superior gain assisted double-negative plasmonic nanoantenna to demonstrate nonlinear
effects in UV/visible region. Demonstration of near-field transmission spectrum reveals the production of the local-field
enhancement up to 102 for half wavelength generation with the incident light wavelength in double nanorod-antenna
(DNRA) system and UV/ white light super-continuum generation for the nanoantenna array (NA) system. Negative real
values of both permeability (μ) and permittivity (ε) with extremely low imaginary values for visible light is obtained by
applying coupled dipole approximation. Near-field and far-field resonance spectrums reveal light amplification and high
directionality for the designed nano-antenna.
An artificial engineered structure of nano-inclusion made of metallic nano-rods embedded in a dielectric
(ε=12.96) matrix with hexagonal arrangement is proposed. New improved designed structure exhibits Negative
Refraction (NR) in visible region by using surface plasmon wave in metallo-dielectric photonic crystal operating in a
dispersion regime with anti-parallel refracted wave vector and Poynting vector. Finite Difference Time Domain (FDTD)
simulations are carried out to study the reflection and transmission properties and obtained Far-field pattern. Designed
structure gives NR with high transmission and act as a filter with a quality factor ≈ 102 with strong application potential
in nano-optics and nano-technology.
A design of polarization beam splitter based on negative refraction in photonic crystal is proposed. The proposed structure is formed by a hexagonal lattice of embedded air holes in silicon materials and is based on 2-D photonic band structure and equi-frequency contour calculations where negative refraction is considered to be function of incident angle and thickness of slab. The designed structure exhibits oppositely signed (negative and positive) refraction for TE and TM polarization at telecom wavelength windows. The wavelength response of the designed PBS is obtained for both polarizations.
