量子通信中的窄脉冲光调制技术

摘要

介绍了应用于量子通信的半导体激光器的窄脉冲激光驱动电路设计方法。该电路利用射频三极管的雪崩效应产生的电脉冲驱动激光二极管，实现了小于1 ns底宽的光脉冲。并在实现窄脉冲的同时实现了对光脉冲峰值功率的调节。%It introduces a laser pulse driving circuit design used in semiconductor lasers for quantum communi -cation .Based on the avalanche effect of the RF transistor , we design the pulse driving circuit which achieves a narrow light pulse with the bottom width of less than 1ns.And also we realize the regulation of the peak power of this narrow pulse .
