Therefore, fast tunable filters are very important in optic communications. In this paper, we try to design multichannel terahertz filters with one dimension photonic crystals because of their simple structure to produce which they have major rule in design of our filter. To reach to the tunable filter in our terahertz filter we use nonlinear Kerr effect. We try to excite the nonlinearity of system by using of laser pump field and then we have tunability in our filter. The channel of proposed Filter shifted 250 micrometer by increasing of injected field intensity. CP - IRAN IN - LG - eng PB - opsi PG - 612 PT - Research YR - 2016
