title: Flexible OTDM to WDM converter enabled by a programmable optical processor.
abstract: We propose an OTDM to WDM converter which enables wavelength tunability, flexible OTDM tributary to WDM channel mapping and modulation format transparency. The converted signals are obtained by four-wave mixing (FWM) the input 160 Gb/s OTDM signal with a multi-wavelength sampling pulse train (SPT). The generation of the multi-wavelength SPT starts by multicasting an optical clock signal. The multicast pulses are then individually delayed and reshaped by a programmable optical processor (POP), resulting in flexible generation of the SPT. Error-free performance was achieved in different OTDM tributary to WDM channel mappings. In addition, intermediate rate conversion (2x80 Gb/s) was also achieved simply by reconfiguring the POP.
