| 1D photonic crystal was fabricated in a dichromate sensitized biopolymer using holography method. The effects of the temperature of the photonic crystal layer on the center of photonic band gaps were studied. We showed that the central wavelength of the band gap can be tuned by heating the photonic crystal layer. By applying such heat treatment, tuning of the position of the band gap for about 80 nm was obtained. |
