Abstract
Chaotic synchronization in injection semiconductor lasers with optical feedback applied to optical secure communications is presented. The two chaotic systems can be synchronized with a gradually process to gradually steady in full space. Synchronous transient response to a pulse of injecting light is studied. Influences of the white noise on the synchronous error, and the synchronous characteristic with optical feedback are studied in detail. Chaos masking with a sinusoidal frequency of 6GHz signal and chaotic injecting shift keying (CISK) in the system are numerically simulated in optical secure communications. The both systems show a good ability of robust security and anti-uncover.
