We experimentally demonstrate several high-speed wavelength division multiplexing (WDM) to time division multiplexing (TDM) conversion schemes by using different nonlinearities in highly nonlinear fiber (HNLF). 40-160-Gb/s WDM-to-TDM conversion using cross-phase modulation (XPM) and 160-320-Gb/s conversion based on supercontinuum generation are shown. Furthermore, we investigate a different kind of HNLF, and demonstrate 40-80-Gb/s WDM-to-TDM conversion using XPM in a 0.8-m bismuth oxide HNLF (Bi-HNLF). Less than 3-dB power penalty is obtained for each case.
