The development of intersubband semiconductor light sources: from MOSFETs to Quantum Cascade Lasers
The development of intersubband semiconductor light sources: from MOSFETs to Quantum Cascade Lasers
Helm, M.
I will present a short history of intersubband light emission from semiconductor quantum structures, starting with MOSFETs in 1976 and culminating with the invention of the quantum cascade laser in 1994. I will discuss the underlying physics and present some highlight achievements.
Nowadays these lasers span a wavelength range between 2.8 and 250 microns, which is nearly two spectral decades.
Keywords: intersubband; quantum cascade laser
