Hmm interesting call. I'll have to look into this further too. Once upon a time I was also into this technology arena. It would be wise to take a look at this company too:

Finisar. The CEO is a pretty good entrepreneur. Talks alot about the market. And the future. However I'm not sure whether the tools of Valdor apply.

There are alot more video's out there about finisar.. so it might be interesting to look at.

Furthermore, I advise you to have a look at Lightwave Logic, another interesting company who is involved with optics. But for CPU's.

Hope I didn't divert your attention too much. Everyone here is going to have to spend alot time doing research to be secure about invest in Valdor.
