Center for Materials and Devices for Information Technology Research
This wiki is a reference collection on photonics. Most of the text has been captured from a series of lectures recorded in 2005-2008 by center faculty Jean-Luc Bredas (Georgia Tech), Neal Armstrong (University of Arizona) and Seth Marder (Georgia Tech). You may also want to search the CMDITR Photonics Digital Libary for individual learning objects.

(check out the OLED section below- the first we are building out)
