L., et al., Index Guiding Dependent Effects in Implant and Oxide Confined Vertical-Cavity Lasers, IEEE Photonics Technology Letters 8, no. 6 (June 1996): 740-742.http://hdl.handle.net/10217/839Implant and oxide confined vertical-cavity surface-emitting lasers are compared in terms of properties dependent upon the nature of index guiding in the two structures including CW threshold current scaling with size, light-current linearity, pulsed operation delay, and beam profiles. The oxide confined lasers, fabricated by wet thermal oxidation, have a built-in index guide and thus exhibit substantially better properties than do lasers from the same wafer fabricated by proton implantation which rely on a thermal lens to reduce diffraction losses.born digitalarticleseng©1996 IEEE.Copyright and other restrictions may apply.
