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.
