Ultra-fast 160:10 Gbit/s time demultiplexing by four wave mixing in 1 m-long B2O3-based fiber

One meter-long spool of bismuth oxide-based fiber, with nonlinear coefficient of 1250 W−1 km−1, is used to realize an optical 160-to-10 Gbit/s demultiplexer based on four wave mixing. Bit-Error-Rate measurements demonstrate a demultiplexing penalty lower than 2 dB confirming the suitability of bismuth oxide-based fiber for 160 Gbit/s all-optical processing.
