Abstract:
1. A method for fabricating a Group-III nitride laser diode, comprising: growing an n-type contact layer on a substrate at a temperature within a first growth temperature range; growing an n-type compliance layer on said n-type contact layer at a temperature within a second growth temperature range that is lower than said first growth temperature; growing a cap layer on said compliance layer at a temperature in said second temperature range to protect said compliance layer from temperatures in said first temperature range used to grow subsequent layers; growing an n-type waveguiding element and on said cap layer at a temperature within said first growth temperature range, said waveguiding element grown with a higher index of refraction compared to laser diodes without said compliance layer; growing an n-type separate confinement heterostructure (SCH) on said n-type waveguiding element; growing an active region on said n-type SCH; growing an undoped layer adjacent said active region on said n-type SCH; growing a p-type SCH on said active region; and growing a p-type waveguiding element on said p-type SCH.
