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 begin to derive Fermi's Golden rule, and we talk about two-level systems, what they mean, why they are useful, and how we can model them using quantum mechanics and the Schrodinger equation. We then start to actually plug things in, and we find a differential equation which we ultimately want to solve. 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.
