High Speed Modulation, Beam Steering and Control of High Power Diode Lasers

摘要

This contract funded a major effort in bringing to maturity, a first- principles theory of semiconductor lasers and amplifiers based on a fully microscopic description of the light semiconductor material coupling. Significant breakthroughs were made at the microscopic physics level by explicitly including all of the relevant excited bands in the active region of the device and obtaining quantitative agreement with gain/index and linewidth enhancement spectra measured for a variety of Quantum Well structures at the Air Force Research Laboratory, Albuquerque, NM. The full nonlinear pde model for high power wide aperture semiconductor lasers was reformulated theoretically so as to take advantage of speed and excellent parallel scaling of our ONYS2 in- house supercomputer. Resulting from this is the first interactive simulator for designing new generations of high brightness semiconductor devices. We were able to begin building a fully interactive platform-independent optoelectronic simulator which should have a major impact on designing sophisticated telecoms systems. Funding also allows major inroads in explaining the novel creation of an optically turbulent atmospheric light guide.
