We demonstrate superior cascadability performance of bit-rate transparent all-optical interferometric wavelength translators compared to optoelectronic translators. For a translator bandwidth of /spl sim/2 times the bit rate, 9 optoelectronic and 75 all-optical translators can be cascaded.
Optical wavelength conversion or wavelength adaptation is a desired functionality for evolving WDM network architectures. The ability to perform routing and switching as a function of wavelength in a network can be achieved through wavelength conversion. The one feature necessary for all wavelength converters is the ability to provide a new wavelength which… (More)
A novel optical translator that can perform 3R-regeneration and wavelength conversion of high-speed return-to-zero signals is demonstrated at 20 Gbit/s. Efficient retiming and bit-error-rate performance is measured using a Mach-Zehnder interferometer with integrated semiconductor optical amplifiers.
