Steady-State Analysis of a Directional Square Lattice Band-Edge Photonic Crystal Lasers

Abstract

The original square-lattice band-edge structure emitted light in different directions. In a recent paper, we have improved the directivity of these structures by using a honeycomb photonic crystal to shield the original structure. This has improved the performance of such devices, in such a way that light can be coupled directionally to a large waveguide. In this paper, we present a steady-state analysis of the performance of this directive device and study the amount of power which can be coupled into the waveguide, analyzing its performance as an in-plane emitter and the limitations caused by vertical losses.
