Detailed experimental investigation of an all-active dual order mode mach-zehnder wavelength converter

摘要

The conversion capability of a new all-active DOMO Mach-Zehnder interferometer has been assessed experimentally at 10 Gbit/s in a co-directional propagation scheme. For signal and CW wavelengths covering the entire EDFA window the converter showed almost wavelength-independent performance, with a high signal-to-noise ratio of the converted signals. Additionally, conversion to the same wavelength, with nearly constant, low excess penalty, was achieved in the wavelength range 1535-1560 nm. A clear and open eye diagram was also obtained at 20 Gbit/s, together with a high input signal suppression ratio, demonstrating that the DOMO converter is an attractive device concept for all-optical wavelength conversion at high bit rates.
