Summary on Grant Application Form |
|
Quantum cascade lasers (QCLs) based on 1114 heterostructures have proved enormously successful as solid-state radiation sources coverir range of infrared wavelengths (from 3 to 24 microns). A QCL operating in the THz band (4.4THz, with a power output of several mW) has al: demonstrated. QCL operation does not involve interband recombination, and therefore the concept is readily transferable to the Si/SiGe mai system. A SUSiGe QCL therefore represents one of the most promising technological routes to realisation of a silicon-based laser. Recent 1 members of this consortium has shown that high quality SUSiGe quantum cascade heterostructures (of up to 100 periods to date) can be gr< virtual substrates. This project incorporates research expertise in silicon-on-silicide-on-insulator (SSOI) technology to develop silicon-based structures and hence realise both edge and surface-emitting Si/SIGe quantum cascade lasers.
