Hi Spacekim,
Serenade of Ansoft does have optical models for linear/nonlinear analysis like laser diode, LED, photon detector, optical fibre and attenuator. Otherwise it is not a dedicated Optical CAD of course.
The optical models are to be filled with real datasheet particulars if a real optical device is to be simulated, because its library does not include manufactured optical components.
I do not know of other serious CADs dealing with optical issues but a search on the web revealed the followings:
EasyOpt Optical CAD Program at kvand.mit.edu/EasyOpt/index.shtml or if you think of optical entities such as lenses, mirrors, prisms etc, then see **broken link removed** .
I do not know these programs though. I hope these are of some help to you.
