Theory of Coupled Resonator Optical Waveguides (CROW) Exhibiting High Order Exceptional Points of Degeneracy
Mohamed Y. Nada, Mohamed A. K. Othman, Filippo Capolino
We present a novel approach and a theoretical framework for generating high order exceptional points of degeneracy (EPD) in photonic structures based on periodic coupled resonators…
The degenerate band edge laser: a new paradigm for coherent light-matter interaction
Mehdi Veysi, Mohamed A. K. Othman, Alexander Figotin +1
We propose a novel class of lasers based on a fourth order exceptional point of degeneracy (EPD) referred to as the degenerate band edge (DBE). EPDs have been found in Parity-Time-…
Giant resonance and anomalous quality factor scaling in coupled resonator optical waveguides at the degenerate band edge
Mohamed Y. Nada, Mohamed A. K. Othman, Ozdal Boyraz +1
We propose a novel scheme for enhancing the quality factor of coupled resonators optical waveguides (CROWs) when operating near a degenerate band edge (DBE). A DBE is a four-mode e…
