Two-dimensional periodically index-coupled fabry perot laser ("2d pic-fl")

Abstract

A two-dimensional periodically index-coupled Fabry Perot laser includes a substrate, a n-cladding layer disposed atop the substrate, a n-waveguide layer disposed atop the n-cladding layer, a p-waveguide layer disposed atop the n-waveguide layer, a quantum well disposed between the n-waveguide layer and the p-waveguide layer, a p-cladding layer disposed atop the p-waveguide layer, a p-contact layer disposed atop the p-cladding layer, and a two-dimensional grating layer is disposed between the p-cladding layer and the p-contact layer. The two-dimensional grating layer comprises a plurality of holes arranged in a pattern with a predetermined grating period. The two-dimensional grating layer defines a first grating area beneath the p-contact layer. The two-dimensional grating layer defines a second grating area surrounding the first grating area.
