We present an approach and a theoretical framework for generating high-order exceptional
points of degeneracy (EPDs) in photonic structures based on periodic coupled resonator …

We propose a novel scheme for enhancing the quality factor (Q factor) of coupled resonators
optical waveguides (CROWs) side coupled to a straight waveguide when operating near a …

Tuneable true time delay device is designed at the degenerate band edge (DBE) by using
two coupled periodic silicon ridge waveguides. The holes of the two ridge waveguides are …

We investigate wave properties in coupled transmission lines (CTLs) under a special
condition known as the exceptional point of degeneracy (EPD) at which two or more of the …

We investigate the modal characteristics of coupled-mode guiding structures in which the
supported eigenmodes coalesce; the condition we refer to as an exceptional point of …

A degenerate band edge is a resonant dispersive behavior of coupled transmission lines
arising from a fourth-order degeneracy due to the coalescence of two propagating and two …

The demand for higher-data-rate, energy efficient, and tunable devices continues to grow as
more and more devices are connected together in the context of internet of things. To sustain …

We propose a novel scheme for enhancing the quality factor of coupled resonators optical

We explore the emergence of exceptional points of degeneracy (EPDs) that denote a
coalescence of multiple eigenmodes in coupled-mode structures. We establish the general …
