Effect of laser li new id th on the channel spacing and error rate in optical frequency division multiplexed systems incorporating semiconductor optica amplifier demultiplexers

الملخص EN

Analysis and performance predictions of optical frequency division multiplexing (OFDM) receivers incorporating semiconductor optical amplifier (SOA) demultiplexer are presented.

The analysis takes into account the influence of finite laser linewidth and various noise sources associated with the optically preamplified delection sysitrtv The results indicate clearly that the normalized crosstalk level must be kept below ■ 1Q.S dB to prevent the occurrence of a bit-error-rate (HER) floor at a level greater than
