Optical Band Structure

https://www.patreon.com/edmundsj If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible. In this video, I talk about where the band diagrams we have been using to this point fall short, and how band structure (or E/k diagrams) are much more useful when dealing with optical transitions. This band structure will allow us to use what we have learned about two-level systems and apply it to figure out the absorption spectrum of a semiconductor. This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley. Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.
