Abstract
In this paper a nonlinear photonic crystal optical limiter structure for TE modes is proposed. The photonic crystal used for this purpose is a triangular lattice of holes in a GaAs substrate. Nonlinear Kerr effect is used to trigger the switching mechanism. A straight forward method for designing the limiter is hereby presented. Finite difference time domain (FDTD) and plane wave expansion (PWE) methods are used to analyze the structure. The nonlinear optical Kerr effect is n2 = 2.7x10-9m 2/W and a switching power of 15W is obtained in this case. There is a 12dB contrast ratio between the ON and OFF states of the limiter.
