Abstract :
Self-frequency conversion of ultrashort optical pulses into arbitrary multiwavelength components without the use of a pump is achieved by using supercontinuum generation. Frequency conversion of a randomly-modulated 1.535-1.560 μm, 2.5 ps pulse stream at 6.3 Gbit/s into 1.41-1.64 μm, 0.29-1.0 ps pulse streams is demonstrated for the first time. The method features ultrawide tunability of over 200 nm, and multiwavelength, pulsewidth-tunable output for flexible WDM distribution networks
