There are 6 modules in this course

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.Module 1 will cover the quantum cascade laser, a laser design based on intersub-band transitions, that enables very long wavelength lasers. It will also talk about lasers that operate on intraband transitions, using low dimensional structures, which enable further control over carrier concentrations.

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.

In this module, you will learn about the basics of detection and the key performance metrics that are used to evaluate detectors including noise equivalent power and detectivity. This lays the building blocks for fundamental understanding, design, and use of different photonic detection technology. This is core information that should be in the wheelhouse of any photonics researcher or engineer.

In this module, you will learn about two powerful detection technologies: charge coupled devices (CCDs) based on metal insulator semiconductor structures and photoconductors. These technologies are very useful for photonic systems.

What's included

5 videos2 readings2 quizzes

In this module, you will learn about another very important detector technology: p-n junctions. These junctions can be used to be photodiodes as well as avalanche photodiodes. We will learn these important technologies function, with applications ranging from microscopy to light detection and ranging (LIDAR).
