Welcome to the home page of the Semiconductor Laser Group. 

The Semiconductor Laser Laboratory in the Micro and Nanotechnology Laboratory at the University of Illinois at Urbana-Champaign was established for research and development of III-V semiconductor lasers and optical devices grown by metalorganic chemical vapor deposition (MOCVD).

    The students and staff of the Semiconductor Laser Laboratory have built and are operating fully-automated MOCVD reactors and are involved in the study of optical processes in various structures such as quantum well heterostructures, superlattices, low threshold single mode lasers, high power index guided laser arrays, self-assembled quantum dots, selective area quantum dots and wires, and other novel 3D quantized structures. They have demonstrated reliable low threshold index guided lasers, integrable distributed feedback lasers, and high power lasers and laser arrays from AlGaAs-GaAs heterostructures and lattice-mismatched strain-accommodated InGaAs-GaAs heterostructures.

    Present research interests include the development of integrated optoelectronic devices by selective area epitaxy, the growth of reduced self-assembled nanostructures, such as quantum wires and dots, development of high power and high performance diode lasers, and the generation of THz radiation by optical heterodyning.
