Abstract

The use of diffused quantum well structures to enhance single transverse mode operation in vertical cavity surface emitting semiconductor lasers is proposed. A step diffused quantum well (DFQW) structure overcomes the influence of spatial hole burning and thermal lensing in vertical cavity surface emitting lasers (VCSEL). It can be realized by using a circular hollow mask to define the DFQW structure.
