we report a novel method for the control of the photonic band gap of photonic crystals(PC).PC waveguides can be obtained by infiltrating silicon resin into the air regions in 2D photonic crystals composed of square lattices of dielectric cylinders.The refractive indices of silicon resin can be changed by temperature.Numerical simulation results show that the band gaps of the photonic crystal can be tuned by temperature manipulation
which can be used for making novel optical switches and field-sensitive polarizers in photonic integrated circuits.
