Abstract

We theoretically analyzed and experimentally demonstrated an injection-locking based all-optical flip-flop memory using a simple and compact tunable V-cavity laser (VCL). A bistable region in the tuning characteristics of the VCL is employed for the flip-flop operation. The state of the VCL can be set and reset by injecting signal pulses at two different wavelengths. The pulse power for both set and reset signal is only about 1 pJ. Short response times of about 150 ps are measured for storing and erasing.

摘要

我们从理论上进行了分析，并通过实验证明了一种基于注入锁定的全光触发器存储器，该存储器使用了一个简单且紧凑的可调谐V型腔激光器（VCL）。VCL调谐特性中的双稳区域被用于触发器操作。通过注入两种不同波长的信号脉冲，可以设置和重置VCL的状态。设置和重置信号的脉冲功率仅约为1皮焦。测量得到存储和擦除的响应时间约为150皮秒，响应时间较短。
