We fabricated phototunable photonic crystals by infiltrating an azobenzen liquid crystal polymer (PLC) into voids of an opal or an inverse opal film. Azochromophores of PLC could be oriented perpendicular to the polarization direction of incident light, causing a change in refractive index of the PLC domain. Consequently, photonic band gap could be reversibly shifted by using the photo-induced molecular orientation. In addition, the photonic band gap in the inverse opal film was sifted larger than that in opal.
