Title:
TWO−DIMENSIONAL PHOTONIC CRYSTAL SURFACE−EMISSION LASER
Document Type and Number:
WIPO Patent Application WO/2003/005513
Kind Code:
A1
Abstract:
Two−dimensional photonic crystal surface−emission laser comprising a two−dimensional photonic crystal, having media different in refractive index arrayed in a two−dimensional cycle, disposed in the vicinity of an active layer that emits light by the injection of carriers, wherein the two−dimensional photonic crystal consists of square lattices having equal lattice intervals in perpendicular directions, and a basic lattice consisting of a square with one medium as a vertex has an asymmetric refractive index distribution with respect to either one of the two diagonals of the basic lattice to thereby emit light in a constant polarizing direction.
