Simultaneous two-distributary-channel demultiplexing of an OTDM signal using a bidirectionally operated highly nonlinear fiber after 100km transmission.

Abstract: A simultaneous two-channel optical time division multiplexing (OTDM) demultiplexing is proposed and experimentally demonstrated by using a bidirectionally operated highly nonlinear fiber (HNLF) followed by a narrow-band offset filter. The performance of the proposed demultiplexer is evaluated in a 40Gb/s OTDM 100km transmission system. A maximum power penalty of 2.4dB is obtained for the worst demultiplexed channel. The proposal might be interesting since it offers a powerful tool for developing ultrafast photonic networks. [Copyright &y& Elsevier]
