We experimentally demonstrate full simultaneous error-free demultiplexing of a 160-Gb/s OTDM data stream to 16x10-Gb/s WDM channels in a single nonlinear optical device. A temporal Fourier processor based upon a four-wave mixing (FWM) time lens is used to perform the demultiplexing operation. The FWM pump pulses are chirped such that they temporally overlap to allow for continuous operation; a necessary feature for full demultiplexing. We identify the fundamental challenges of operating in this continuous regime and characterize their impact on the system performance. We determine the main performance impairments to be crosstalk from adjacent WDM channels and crosstalk arising from non-degenerate FWM amongst the OTDM signal and the temporally overlapping pump pulses.
