Low-threshold interband cascade lasers operating above room temperature

摘要

Mid-IR type-II interband cascade lasers were demonstrated in pulsed mode at temperatures up to 325 K and in continuous mode up to 200 K. At 80 K, the threshold current density was 8.9 A/cm(2) and a continuous wave output power of similar to140 mW/facet was obtained. (C) 2003 Elsevier B.V. All rights reserved. [References: 13]
