提出并详细分析了一种基于时分复用技术倍乘光脉冲重复率的方法：在２×２光纤耦合器的一个输入口与一个输出口间，接入时延为脉冲列半周期奇数倍的一段光纤使之形成环状连接循环耦合，而在另一输出口获得光脉冲。详细分析了该系统中光纤耦合器耦合比、插入损耗、时延光纤长度的要求，偏差的影响及其调节法，给出了理论公式、结果的计算机模拟与实验介绍；与经典的马赫陈德尔干涉仪接法及近年提出的Ｓａｇｎａｃ环接法进行了比较。该方法特别适用于对窄脉冲列进行串接复用实现重复率的多次倍乘，从而得到数千兆赫至上百千兆赫的高重复率光脉冲
A method of multiplying the optical pulse repetition rate based on the time division multiplexing technique is proposed and analyzed in detail. The access delay between an input port and an output port of a 2 × 2 fiber coupler is an odd number of times A length of fiber is circled by a ring-shaped connection, and a light pulse is obtained at the other output port. The coupling ratio of optical fiber coupler, insertion loss, the length of optical fiber, the influence of deviation and its adjustment method are analyzed in detail. The computer simulation and experimental introduction of theoretical formula and result are given. Compared with classical Mach-Chen The Delta interferometer method and the Sagnac loop method proposed in recent years are compared. The method is particularly suitable for multiple pulse multiplication of narrow pulse trains to achieve multiple repetition rate multiplications, resulting in high repetition rate optical pulses of several gigahertz to hundreds of gigahertz
