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 show why fabry-perot cavities are so cool and ubiquitous - they can build self-sustaining electric fields from virtually zero input. They can also massively amplify an incoming electric field, only constrained by the amount of current you are willing to send in. For those of you who know a bit about electromagnetics, you will notice I ignored the phase accumulation during propagation to simplify things, although really you should include that.
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.
