Abstract :
A new, coupled-mode formalism based, analytical approximation for array modes in perfectly-periodic 1D photonic devices (photonic crystal lattices and superlattices) is presented. We consider the specific class of 1D photonic crystals (encompassing large arrays of coupled planar waveguides, phase-locked lasers etc.), in which light propagates along the optical axis of the device. Approximate analytical expressions for the array modes (both spatial distribution and propagation constants) become available. This approach allows a fast, simple and accurate analytical evaluation of the electromagnetic field in 1D photonic crystal devices.
