High Performance Epi-Side-Up-Mounted Interband Cascade Lasers

Maxion proposes to further develop epi-side-up-mounted interband cascade (IC) lasers emitting in the mid-infrared (IR) wavelength spectral region between 3 and 5 microns. Following up on a successful Phase I effort, Maxion will design, develop,and testimproved IC laser active regions that promise to lead to reductions in threshold current density and non-radiative processes including Auger recombination, which presently limit the performance of state-of-the-art designs. In addition to modified activeregion designs, Maxion will investigate modified waveguide designs and device fabrication details intended to decrease internal losses, reduce surface recombination, and increase optical confinement factors to further enhance high temperature performance.Prior to the project''s conclusion, Maxion expects to have developed epi-side-up-mounted IC lasers capable of continuous wave operation at heat sink temperatures exceeding 260 K with emitted powers exceeding 20 mW from a single IC laser facet.
