So my Google skills must be getting rusty because I can't find any good information on what Optical Engineers exactly do. I've narrowed it down to design optical systems.. and that's about it. I don't know the job prospects (are they in demand? are they too niche?). I don't really know what they're all about other than learning about and manipulating light to do things we want them to do. Assuming I'm not growing more incompetent with searches, does anyone have any personal experience with the field or any knowledge about the career beside the basic summaries on the optical societies' webpages?
