All-optical intensity noise suppression for solid-state and semiconductor lasers
Journal of Telecommunications and Information Technology, 2005 This paper will report on a new all-optical technique of relative intensity noise (RIN) suppression for solidstate and semiconductor lasers. The new scheme we have used is based on an unbalanced Mach-Zehnder interferometer (UMZI), which is able to ...
