0.5Gbits/s message bidirectional encryption and decryption based on two synchronized chaotic semiconductor lasers

摘要

A bidirectional chaos communication system, composed of 1550nm semiconductor lasers (SLs) and fiber links, is experimentally and numerically investigated. Based on the robust chaos synchronization between two authorized SLs, 0.5Gbits/s pseudo-random data bidirectional message transmission between the two SLs has been preliminarily realized experimentally. Moreover, related theoretical simulations are also given, which basically conforms to our experimental observations.
