Quantum Cascade Lasers

The course covers the basics of nanophotonic light emitting devices and optical detectors, including metal semiconductor, metal semiconductor insulator, and pn junctions, photoconductors, avalanche photodiodes and photomultiplier tubes. Low dimensional structures enable an entirely new class of devices. Join me on a journey to understand how this happens and explore powerful examples of successful technologies such as the quantum cascade laser....

Confined photons

In this unit, we will learn how to confine photons just as we do with electrons. This gives us power over the allowed modes of emission, allowing us to enhance the performance of lasers as well as develop 'threshold-less' lasers. I hope you enjoy this exciting topic as much as I do....
