Patent ID: 8012780

Claim:
A method of fabricating a semiconductor laser including a two-dimensional photonic crystal, the method comprising the steps of: growing an In X1 Ga 1−X1 N (0<X1<1) layer on a gallium nitride-based semiconductor region in a reactor to form a substrate product; after taking out, from the reactor, the substrate product including the In X1 Ga 1−X1 N layer, forming a plurality of openings for a two-dimensional diffraction grating of the two-dimensional photonic crystal in the In X1 Ga 1−X1 N layer to form a patterned In X1 Ga 1−X1 N layer; and growing an Al X2 Ga 1−X2 N (0≦X2≦1) layer on the patterned In X1 Ga 1−X1 N layer so as to form voids from the openings.
