Time domain add-drop multiplexing for RZ-DPSK OTDM signals.

We show all-optical time domain add-drop multiplexing for a phase modulated OTDM signal for the first time, to our knowledge. The add-drop multiplexer is constructed of a Kerr shutter consisting of a 375 m long highly nonlinear fiber (HNLF), gamma=20 W(-1)km(-1). Successful time domain add-drop multiplexing is shown for 80 Gb/s RZ-DPSK OTDM signals with a 10 Gb/s base rate.
