We report broadband operation of an all-optical wavelength shifter, performing simultaneous drop and wavelength-conversion of a burst of OOK data selected by an optical gate. The device operates entirely in the photonic domain and is based on a single Semiconductor Optical Amplifier Mach-Zehnder Interferometer. The circuit is suitable for dynamic wavelength routing and add/drop operation in WDM systems...
We report an extensive experimental wavelength characterization of a scheme for all-optical gated wavelength shifting operation. This scheme is suitable for dynamic wavelength routing and add or drop operation in wavelength-division multiplexing systems and optical packet switched networks. A single semiconductor-optical amplifier Mach–Zehnder interferometer with a multi-inputs configuration is exploited...
