4×10Gb/s wavelength multicasting with tunable NRZ-to-RZ pulse format conversion using time- and wavelength-interleaved pulses

We demonstrate 4×10Gb/s simultaneous wavelength multicasting and NRZ-to-RZ pulse format conversion with tunable duty cycle. Multicasting is achieved by four-wave mixing of the input signal with a time- and wavelength-interleaved laser source, while the format conversion is obtained through the use o...

Summary:We demonstrate 4×10Gb/s simultaneous wavelength multicasting and NRZ-to-RZ pulse format conversion with tunable duty cycle. Multicasting is achieved by four-wave mixing of the input signal with a time- and wavelength-interleaved laser source, while the format conversion is obtained through the use of a pulsed probe. The input data are copied to four multicast outputs with a common relative delay time. Error-free operations have been obtained in all the outputs with power penalties ranging from − 0.5 to 0.5dB. Output duty cycles with a tuning range of 4.3ps have been achieved.
