Abstract：

In this paper, an all-optical bistable switching operation of resonant-tunneling devices with ultra-small photonic crystal cavity was demonstrated. The whole structure was based on a square lattice photonic crystal formed by rods of refractive index n_r=3.4 in an air background. The cavity was surrounded by eight nonlinear rods of refractive index n_L0=3.1 and nonlinear Kerr coefficient n₂=9×10⁻¹⁷W/m². Nonlinear finite difference time domain method was used to get a bistability hysteresis loop. Next, all-optical wavelength controlled power source (WCPS), hard-limiter and switching operation based on optical nonlinearity were shown. And that small cavity structure has a small length of 12 mm. Considering the numerous applications and small length, this proposed structure has various potential function in all-optical circuits.

Key words： all-optical bistability Kerr nonlinearity photonic crystal cavity switching
