Abstract
An all-optical ADD-DROP multiplexer able to carry out ultrafast channel extraction, clearing, and insertion operations for time-interleaved optical signals is presented. The proposed ADD-DROP multiplexer exploits polarization rotation induced by cross-phase modulation in 1-m-long highly nonlinear bismuth oxide-based optical fiber with a nonlinear coefficient of 1250 W-1 · km-1. Penalties lower than 1.5 dB in a 4 × 10 Gb/s optical-time-division-multiplexed system have been measured for all operations.
