Metaheuristic approach enabled mode order conversion in photonic crystals: numerical design and experimental realization
(Institute of Physics Publishing, 2019)
In the presented study, we proposed a design approach based on optimization algorithm to obtain mode order conversion in photonic crystal (PC) structures and experimentally verify the numerical result of the corresponding ...
Broadband asymmetric light transmission based on all-dielectric metasurfaces in the visible spectrum
(IOP PUBLISHING LTD, 2019-05)
An asymmetric transmission device composed of all dielectric phase gradient metasurfaces on the dielectric substrate in the visible wavelengths is proposed and designed. In order to verify its operation principle and ...
An Optical Sensor Design Using Surface Modes of Low-Symmetric Photonic Crystals
(Institute of Electrical and Electronics Engineers Inc., 2019)
In this paper, an optical sensor design is proposed with low-symmetric photonic crystals that support surface modes. In order to obtain low symmetry, rotational symmetry is broken within the unit cell size while translational ...
Spectral splitting for an InGaP/GaAs parallel junction solar cell
( OSA - The Optical Society, 2019)
In this paper, a design of a diffractive optical element to split the solar spectrum into two separate parts for a laterally arrayed InGaP/GaAs solar cell is presented. Optical simulation is done by using the three-dimensional ...
A reduced symmetric 2D photonic crystal cavity with wavelength tunability
(Institute of Physics Publishing, 2019)
In this paper, we propose a microcavity supported by a designed photonic crystal structure that provides both tunability of cavity modes and the cavity's quality factor. A low symmetric defect region provides a trigger ...
