Center for Materials and Devices for Information Technology Research (CMDITR) Wiki
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.
