摘要

An optical bistable switch based on a photonic crystal resonator using the nonlinear effect of a chalcogenide glass in a rectangular defect cavity is proposed and investigated numerically. The influences of the designed cavity and refractive index of the Kerr nonlinear medium on the transmission of the resonator are analyzed precisely through finite-difference time-domain simulation. The simulation results show that our compact structure possesses excellent switching characteristics by tuning the incident electric intensity. The properties of the optical bistability are investigated at the resonance wavelength with three different detuning parameters. In addition, the results show that this switch has a wide operating wavelength regime and fast operation speed of 90 Gb/s. Considering numerous characteristics, such a high-speed switch can find application for all-optical devices.
