| Popis: |
All-optical polarization switches exploiting the subpicosecond response time of the Kerr effect in glass fibers are promising for future multi-hundred-Gb/s transmission systems. The maximum switching rate of such Kerr shutters can be increased by reduction of the fiber length with higher pump (gate) powers, by using shorter pulse durations, and by closer frequency separation of the pump and probe pulses in the vicinity of the zero group velocity dispersion wavelength. In a previous work using picosecond pulses we demonstrated ultrafast demultiplexing based on induced polarization rotation at 170 Gb/s1. We present here results obtained with femtosecond gate and probe pulses which permit demultiplexing at switching rates as high as 460 Gb/s in a single-mode fiber. Although larger fiber lengths reduce the switching power, their application simultaneously increases the latency of a future communication system. This motivated us to investigate relatively short fibers with lengths comparable to the walk-off length. |
