Abstract

40Gbit/s all-optical format conversion from the carrier-suppressed return-to-zero (CS-RZ) to the non-return-to-zero (NRZ) is proposed and demonstrated with a temperature-controlled all-fiber delay interferometer (DI) and narrow-band filters. The NRZ signals can be achieved at two different wavelengths simultaneously from the original CS-RZ, with polarization and input power independence. The operation principle is theoretical analyzed with the help of numerical simulation and spectra analysis. Simulated results are well coincidence with experimental results. The format conversion can be achieved with power penalty of 1.6dB
