High-power and high-efficiency midwave-infrared interband cascade lasers

A ten-stage interband cascade laser emitting at 3.3 - 3.6 μ m exhibits a voltage drop only 4% above the theoretical minimum, and operates to room temperature in pulsed mode. At 78 K , a five-stage device mounted epitaxial-side-up with coated facets has a maximum cw wallplug efficiency of 21%, and a...
