Coupled Mode Theory (CMT) is a well-established formalism, which is widely used in the computation of the optical characteristics of photonic devices, matching the model of array of parallel waveguides [1]-[6]. In particular, it is applicable to 2D photonic crystal devices (i.e. arrays of coupled waveguides / phased laser arrays), in which light propagates along the optical axis of the component....
Coupled Mode Theory (CMT) is a well-established formalism widely used in the analysis of propagation and interaction of electromagnetic modes in arrays of parallel waveguides, coupled resonator optical waveguides (CROWs), phase-locked arrays of VCSELs etc. So far, CMT analysis considered only situations where both the dielectric function and the input optical signal were assumed to be time-independent...
We show mathematically that the lowest-order supermode of a real-refractive-index phase-locked semiconductor diode laser array, which radiates into a single narrow far-field lobe, is favoured by its lower threshold when the gain in the interspaces between the waveguides exceeds that of the waveguides themselves.
