An equivalent electrical model was proposed for simulating the transient responses of a photonic switch cell by analyzing its physical structure.A high-speed driving control circuit was designed for a photonic switch matrix based on the model,and the effect of voltage spikes on the transient response of photonic switch cell was analyzed by simulation.The test results show that the rise/fall time of the signal supplied by the driving circuit are 1.7/1.6 ns,which meets the requirements for nanosecond-level switching of high-speed photonic switches.The switching time of the photonic switch matrix reaches 2.1-5.9 ns with the assistance of the driving control circuits,realizing a high-speed optical switching system.
