Vertical emitting lasers based on 2D Photonic Crystal heterostructure coupled to strip silicon waveguide

Abstract

We fabricate a compact 2D photonic crystal (PC) vertical emitting laser at 1.5 mum, based on slow Bloch mode confinement in a 20 PC heterostructure. The 2D PC, consisting of a square lattice of indium phosphide (InP) micropillar, is bonded on a silicon/silica Bragg mirror. We study the coupling between the 2D PC heterostructure and a silicon strip waveguide around the lasing wavelength.
