Abstract:Existing high-power semiconductor lasers widely use asymmetric large cavity structures or designs with short cavity lengths to enhance device performance, inevitably increasing the device threshold current density and suppressing further improvement of device performance. We have utilized rate equations analysis to investigate the impact of threshold current density on the threshold characteristic temperature of GaAsbased laser diodes at short wavelengths. A simplified carrier escape model has been employed, w… Show more
