摘要
通过分析光开关单元的物理结构,提出等效电学模型,用于模拟光开关单元的瞬态响应.基于该模型,针对光开关阵列设计高速驱动控制电路,结合仿真探究电压尖峰对光开关单元瞬态响应的影响.系统测试结果表明,驱动电路施加的电压信号的上升/下降时间为1.7/1.6 ns,能够满足高速光开关纳秒级切换速度的需求.在该驱动电路的配合下,光开关阵列的切换时间为2.1~5.9 ns,实现了较先进的高速光交换系统.
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.
