Non-Hermitian potentials, as known since a decade, can favor unidirectionality of the flows in one and two-dimensional systems. Inspired by such counterintuitive property of non-Hermitian potential, we propose a novel ...
Chiral modes in 2D PT-symmetric nanostructures
(Springer Science and Business Media, LLC, 2016)
We propose a 2-dimensonal PT-symmetric photonic honeycomb structure that supports chiral Block-likemodes being its excitation input and frequency dependent. We show that while the fundamental resonant frequency excites the ...
Nonreciprocal light transmission in gain-loss modulated Micro ring resonators
(IEEE Computer Society, 2015)
We propose a new type of add-drop Micro ring resonator that is made up of gain and loss materials. In all-dielectric linear systems, light transmission is reciprocal: A symmetric transmission spectrum is observed when an ...
Self-collimation in 2D complex and PT-symmetric media
(IEEE Computer Society, 2015-08)
We study propagation light beams in 2D photonic periodic nanostructures with both index and gain/loss modulations. We determine the conditions for complex periodic media with in-phase gain and index modulations to support ...
Asymmetric transmission from a 2D PT-symmetric honeycomb nanostructure
(IEEE Computer Society, 2014)
We propose a simple realization of a 2-dimensonal (2D) PT-symmetric photonic structure: a honeycomb arrangement of alternating cylinders with gain or loss in a dielectric background. The structure provides a periodic ...
Asymmetric light transmission by using 2D PT-symmetric photonic nanostructure
(Institute of Electrical and Electronics Engineers Inc., 2014-12)
We propose for the first time a simple realization of a two-dimensional Parity-Time symmetric hexagonal shaped photonic structure composed of honeycomb lattice. The structure has a symmetric periodic modulation of the ...
