摘要
We have fabricated GaInAs/AlInAs strain-compensated quantum cascade lasers with InP and GaInAs cladding layers using solid-source molecular-beam epitaxy (MBE). Low threshold current densities and high temperature operation of uncoated devices, with a record value of 490 K, have been achieved in pulsed mode.
