Patent ID: 7760787

Claim:
A method of producing a surface emitting laser device, said surface emitting laser device, including a first resonance region that has an active layer and resonance spacer layers provided on two sides of the active layer; two distributed Bragg reflectors that sandwich the resonance region and face each other wherein each of the distributed Bragg reflectors has periodically stacked low refractive index layers and high refractive index layers; and a current confinement structure that defines a current injection region for injecting a current into the active layer; wherein at least one of the distributed Bragg reflectors includes a second resonance region, and the second resonance region is arranged in the current injection region excluding a predetermined region surrounding a center of the current injection region; the second resonance region includes a resonance spacer layer having a refractive index higher than the refractive index of the low refractive index layers in the distributed Bragg reflectors; and the resonance spacer layer in the second resonance region has a thickness equaling m/2n of a laser oscillation wavelength, where m is an integer and n is the refractive index of the spacer layer in the second resonance region; said method comprising: a step of forming the second resonance region in at least one of the distributed Bragg reflectors; wherein the step of forming the second resonance region includes a first crystal growing step of forming a semiconductor layer for use of the resonance spacer layer to a thickness greater than a predetermined thickness by ¼n of the laser oscillation wavelength; a step of etching and removing the semiconductor layer in the predetermined region without the second resonance region; and a second crystal growing step of, after the step of etching and removing, forming another semiconductor layer having a thickness equaling ¼n of the laser oscillation wavelength.
