The physical principles for the transmission characteristics of the one-dimensional voltage-controlled photonic crystals (VCPC) had demonstrated thanks to the transfer matrix method. It has been shown that we can control the voltage to change the lattice constant, a great impact on photonic band gap, to design the one-dimensional photonic band-gap width (PBW). The relationship between PBW migration and voltage has been obtained. According to different situations, we can design different photonic crystal waveguide filter based on VCPC characteristic.
