Quantum Cascade lasers: Recent advances and future prospects

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Quantum Cascade (QC) lasers are a rapidly evolving mid-infrared and THz semiconductor laser technology based on intersubband transitions in multiple coupled quantum wells. The lasers' strengths are their wavelength tailorability, high performance and fascinating design potential. We will discuss several recent highlights, such as the quest for high performance QC lasers, especially high efficiency and single-mode operation, artificially broadened gain, and the implementation of unconventional laser schemes. We will also briefly discuss several high potential applications in mid-infrared trace chemical sensing.
