Temperature dependence properties of holographic gratings in phenanthrenquinone doped poly(methyl methacrylate) photopolymers.

We examine the temperature dependence of edge-illuminated holographic filters formed in phenanthrenquinone doped poly(methyl methacrylate) (PQ/PMMA) operating at 1550 nm. It was found that the thermally induced change to the refractive index and volume can be used to select the wavelength filtered by the grating. The temperature can be varied over a range of 15 degrees C without introducing noticeable hysteresis effects. The wavelength can be tuned at a rate of 0.03 nm/degrees C over this temperature range. A model for the temperature tuning effect is presented and compared to experimental results.
