Photochromic materials + Silicon?

  1. Mar 31, 2007 #1
    I was wondering whether it is possible to use photochromatic switching effects, for photonic structures on silicon.

    The problem might be that silicon is not transparent for the same wavelengths as photochromic materials. So basically, I was wondering if somebody knew about applications where photochromic materials are used together with silicon, and if there are certain adjustments to circumvene the spectrum problem. A search in the literature has given me nothing so far.

    I would think most photochromic materials would be too slow to respond to a light input to make them useful in photonic applications. As to silicon; it is transparent at wavelengths grater than 1.1 um which would make it ideal for many photonic applications.
