Abstract
Laser diodes are formed using composite material systems which result in the decoupling of the refractive index and band gap profiles of the structures formed with such systems. Laser diodes with composite material systems are described which produce desirable large diameter laser beams and low beam divergence through independent control of the two profiles.
