Abstract:We build a forward error correction (FEC) module and implement it in an optical signal processing experiment. The experiment consists of two cascaded nonlinear optical signal processes, 160 Gbit/s all optical wavelength conversion based on the cross phase modulation (XPM) in a silicon nanowire and subsequent 160 Gbit/s-to-10 Gbit/s demultiplexing in a highly nonlinear fiber (HNLF). The XPM based all optical wavelength conversion in silicon is achieved by off-center filtering the red shifted sideband on the CW probe. We thoroughly demonstrate and verify that the FEC code operates correctly after the optical signal processing, yielding truly error-free 150 Gbit/s (excl. overhead) optically signal processed data after the two cascaded nonlinear processes.

“…Experiments relying on nonlinear optical signal processing have only very rarely actually employed a FEC module. Wavelength conversion is interesting to test with FEC, since it processes all the bits in the data stream in one go, and to the best of our knowledge this has only been done at 10 Gbit/s [2] and not for ultra-high bit rates yet.…”
