Low threshold current 780 nm InAlGaAs/AlGaAs-strained QW lasers and the integration with a passive, non-absorbing tapered mode-size transformer

Abstract

Summary form only given. In AlGaAs/AlGaAs QW lasers operating at 780 nm have been realised with threshold currents down to 8.2 mA. The monolithic integration with a passive, non-absorbing mode-size transformer has been demonstrated for the first time.
