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 ...
Highly controlled Bloch wave propagation in surfaces with broken symmetry
(OSA - The Optical Society, 2018-06-01)
We propose and demonstrate reduced symmetry photonic surfaces providing highly controlled Bloch wave propagation. The backward and dual directional propagations have been observed in the proposed low-symmetric periodic ...
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 ...
Inverse design of integrated photonic structures
(IEEE Computer Society, 2019)
Designs of photonic devices have been mainly based on intuitive and brute-force approach. However, there has been increasing demand in photonics to obtain high device performance and improved functionalities along with ...
