  • CREOL Seminar: Design Issues and Physics for High-Performance Quantum-Cascade Lasers by Dr. Ted Masselink

    CREOL: 102 and Virtual

    ABSTRACT: Quantum-cascade lasers (QCLs) are lasers whose optical transitions are between different subbands of the conduction band of a semiconductor heterostructure. Because the laser transition takes place between different spatially quantized subbands of the conduction band, the emission wavelength is determined by the structure and is not by the band gap of the materials used. Today QCLs emit with a …
