All-optical format conversion from inverse-return-to-zero to non-return-to-zero using a Mach-Zehnder delay interferometer

Abstract

All-optical format conversion from inverse-return- to-zero inverse-RZ to non-return-to-zero NRZ is realized by using a half-bit-delay Mach-Zehnder delay interferometer. Experimental results demonstrate that the converted NRZ signal has better receiver sensitivity than the back-to-back inverse-RZ signal. © 2008 Society of Photo-Optical Instrumentation Engineers.
