Summary on Grant Application Form
Quantum cascade lasers (QCLs) based on III-V heterostructures have proved enormously successful as solid-state radiation sources covering a wide 1 infrared wavelengths (from 3 to 24 microns). A QCL operating in the THz band (4.4THz, with a power output of several mW) has also been demonstra QCL operation does not involve interband recombination, and therefore the concept is readily transferable to the SUSiGe materials system. A SUSiGe C therefore represents one of the most promising technological routes to realisation of a silicon-based laser. Recent work by members of this consortium shown that high quality Si/SiGe quantum cascade heterostructures (of up to 100 periods to date) can be grown on virtual substrates. This project incoi research expertise in silicon-on-silicide-on-insulator (SSOI) technology to develop silicon-based laser cavity structures and hence realise both edge anc surface-emitting SUSIGe quantum cascade lasers.
