All-optical 40 Gbit/s OTDM to 2/spl times/20 Gbit/s WDM signal-format translation

摘要

40 Gbit/s OTDM to 2/spl times/20 Gbit/s WDM signal-format translation is demonstrated using a cross-gain modulation in a semiconductor optical amplifier designed for high-speed operation. Excellent performance is demonstrated by polarisation-independent operation, showing clear eye diagrams and high extinction ratios for the translated WDM-channels.
