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...
Presented are here new, approximate, methods for the calculation of photonic supermodes in 1D photonic devices (arrays of coupled planar waveguides, phase-locked arrays of lasers etc.), in which light propagates mainly along the optical axis of the array. These methods propose a simple, fast and quite accurate way for the estimation and prediction of the spatial distribution of the EM field in 1D...
