Broadband self-collimation in C2 symmetric photonic crystals
(OSA - The Optical Society, 2018-06-01)
In this study, we report a low-symmetric photonic crystal (PhC) structure that exhibits high coupling efficiency in a broadband frequency range with a tilted self-collimating capability. First, the analytical approach is ...
Ultracompact Photonic Structure Design for Strong Light Confinement and Coupling Into Nanowaveguide
(Institute of Electrical and Electronics Engineers Inc., 2018-07-15)
Different optimization algorithms have recently been utilized to design and improve the performance of many nanophotonic structures. We present the design of a compact photonic structure by an approach based on machine ...
Full utilization of semi-Dirac cones in photonics
(American Physical Society, 2018-05-16)
In this study, realization and applications of anisotropic zero-refractive-index materials are proposed by exposing the unit cells of photonic crystals that exhibit Dirac-like cone dispersion to rotational symmetry reduction. ...
Broadband direction-dependent transmission of light with photonic crystal heterostructure grating
(IOP Publishing Ltd., 2018-01-17)
Direction-dependent light transmission is a remarkable phenomenon owing to its great potential to be used in optical communication processing systems such as optical diodes, isolators and rectifiers. All these applications ...
