Slab Waveguide Explained

  / edmundsj   If you want to see more of these videos, or would like to say thanks for this one, the best way to 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. The slab waveguide is the simplest and most important waveguide model you will ever learn. By analyzing the slab waveguide we can understand how interference causes self-perpetuating patters, known as modes, to successfully propagate down the waveguide. These modes are at the core of all waveguides, and understanding when they exist and how to arrive at them will allow you to grasp more complex waveguides and optical systems. 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.
