A novel optical-control terahertz wave modulator based on compound triangular lattice photonic crystal is proposed. The modulator adopts a combined structure of point defect and line defect, and by filling in nonlinear optical material called polyaniline, on-off modulation of terahertz wave is realized. The simulation with Rsoft software indicates that this combined structure has a modulation rate of 10GHz, an extinction ratio of 21.7dB and an insertion loss of 0.31dB. The new optical-control photonic crystal modulator is of a significant value in the future THz communication system.
