WDM-to-OTDM Conversion Using Supercontinuum Generation in a Highly Nonlinear Fiber

We demonstrated an all-optical wavelength-division-multiplexing (WDM)-to-optical-time-division-multiplexing (OTDM) conversion using spectral broadening of super continuum (SC) generation in a highly nonlinear fiber. Four 10-Gb/s WDM channels were injected into time delay blocks for controlling the timing among them, and converted to OTDM channel by the SC-based multiplexing. The SC generation had advantages of eliminated the use of any pump in the WDMto-OTDM conversion. All OTDM demultiplexed optical signals achieved error-free performance with <;2-dB power penalty at BER = 10^-9 compared with the back-to-back signal.
