1. Electric Field Domains in Quantum Cascade Lasers
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : Quantum cascade lasers (QCLs) are periodic semiconductor heterostructures, capable of producing laser gain. They have become an important source of coherent radiation in the mid infrared, and THz frequency regions. QCLs are non-linear electric devices, and often have bias regions of negative differential resistivity (NDR). READ MORE
