Abstract

This paper presents an approximate method of the analysis of two-dimensional triangular lattice photonic crystal laser operation above the threshold. Described approach is based on the coupled wave equations and the energy theorem. It includes gain saturation and spatial hole burning effects and takes into account surface emission losses. An expression is derived for the small signal gain coefficient for transverse magnetic modes as a function of the output power, losses, coupling strength. For the given structure parameters, obtained laser characteristics reveal optimal coupling strength, which indicates maximal power efficiency of the laser structure.
