摘要：

We demonstrate incoherent light emission peaked at lambda = 3.3 mu m from a 15-stage interband cascade active region. The interband cascade light emitting devices with mesa diameters ranging from 50 to 400 mu m were mounted epitaxial-side-down, and light was extracted from the substrate side. At an applied bias of 8.7V and injection current of 0.6 A, and without any measures taken to improve the poor out-coupling efficiency caused by total internal reflection, a 400-mu m-diameter device produced 1.6 mW of continuous-wave output power at T = 25 degrees C. Mesas with smaller diameters displayed emission intensities as high as 1.7 W/cm(2). (C) 2014 AIP Publishing LLC.
