I'm looking for a good semiconductor optics textbook. I have Klingshirn's text, which has problems, but no solutions. As I'm using the textbook outside of university, I need solutions to problems, since I won't know if I'm right or wrong otherwise. I've also looked into Semiconductor Optics and Transport Phenomena by Schafer, but as far as I know this only has problem "hints" and no solutions. I was also unable to find a solution manual for this text. If anyone knows of a good semiconductor optics book with problems AND solutions, I would greatly appreciate it.
