DFG Research Grant: Terahertz Quantum Cascade Lasers Based on InxGa1-xAs/InyGa1-yAs Strain-Compensated Heterostructures on InP Operating Near Room Temperature


The objective of this research is to demonstrate and investigate terahertz quantum cascade lasers based on a novel InGaAs-based active region. Indications are that lasers using this new design will operate near room-temperature; operation of THz QCLs at such high temperatures has not yet been demonstrated and would represent a revolutionary advance for terahertz instrumentation, opening new possibilities in terahertz research and applications.The objective of this research is to demonstrate and investigate terahertz quantum cascade lasers based on a novel InGaAs-based active region.
