Review of Robust Data Exchange Using Optical Nonlinearities

Figure 30

Experimental setup for the demultiplexing of a DPSK OTDM signal and the orthogonal tributary channel exchange of a pol-muxed DPSK OTDM signal. HNLF: highly nonlinear fiber; MLL: mode-locked laser; EDFA: erbium-doped fiber amplifier; ODL: optical tunable delay line; BPF: band-pass filter; PC: polarization controller; PM: phase modulator; MUX: multiplexing; OC: optical coupler; VOA: variable optical attenuator; PoL.: polarizer; Rx: receiver.
