摘要:
Laser emission is reported for the first time from a 10 monolayer-wide highly strained (3.2%) InAs single quantum well confined by Ga0.47In0.53As layers. At 80 K the emission spectrum of broad-area laser diodes is centred at 1.836 mum, the threshold current-density is approximately 500 A/cm2 and the characteristic temperature is T0 congruent-to 30 K. CW operation is achieved up to 110 K with narrow-stripe devices but at shorter wave-length, due to increased losses and filling of the quantum-well energy levels.
