Analytical approximation for photonic array modes in two-dimensional photonic crystal lattices.

We presented here a comprehensive analytical approximation, describing array modes (both the modal fields and their associated propagation constants) in 2D photonic lattices (i.e., arrays of identical coupled waveguides/lasers).

Analytical approximation for photonic array modes in 1D photonic crystal superlattices.

We present a comprehensive analytical approximation for array modes (both the modal fields and their associated propagation constants) for 1D photonic crystal superlattices (i.e., large periodic arrays of repeated sequences of different coupled waveguides/lasers).

Analytical approximation for photonic array modes in one-dimensional photonic crystal devices.

A new analytical approximation for photonic array modes is presented. We consider the specific class of one-dimensional (1D) photonic crystals (encompassing large arrays of coupled identical planar waveguides, large arrays of identical phase-locked lasers, etc.), in which light propagates along the optical axis of the device.

Omnidirectional reflection in several frequency ranges of one-dimensional photonic crystals.

We investigate omnidirectional reflection from higher-order gaps in one-dimensional photonic crystals. Moreover, we present a designing criterion for omnidirectional reflection from several distinct gaps simultaneously, using only a single photonic crystal with a constant period. We show that for practical values of photonic crystals parameters, several relatively large omnidirectional gaps may be obtained.
