We investigate the transverse mode pattern in GaN quantum-well (QW) laser diode (LD) by numerical calculation. We optimize the current GaN LD structure by varying the n-GaN layer thickness. The n-type GaN layer is...

High quality GaN films on (0001) sapphire substrates were grown by a commercial MOCVD system (Thomas Swan Corp.).The etch pits and threading dislocations(TDs) in GaN films have been studied by chemical etching methods...
Waveguide characteristics of symmetrical separate confinement heterojunction multi quantum well (SCH MQW) AlGaN/GaN/InGaN laser diode (LD) are studied by using one dimensional (1 D) transfer matrix waveguide appro...
