Error-free all-optical add-drop multiplexing using HNLF in a NOLM at 160 Gbit/s - Electronics Letters

Introduction: An add-drop multiplexer (ADM) is one of the key elements in optical time division multiplexed (OTDM) networks. Various methods of performing OTDM add-drop have been demonstrated. Recently add-drop operation at 16 10 Gbit=s has been demonstrated with the use of a gain transparent ultrafast nonlinear interferometer (GT-UNI) [1] switch and at 4 40 Gbit=s with travelling-wave electroa...

Numerical investigation of all-optical add-drop multiplexing for spectrally overlapping OFDM signals.

We propose a novel architecture for all-optical add-drop multiplexing of OFDM signals. Sub-channel extraction is achieved by means of waveform replication and coherent subtraction from the OFDM super-channel. Numerical simulations have been carried out to benchmark the performance of the architecture against critical design parameters.

All-optical add-drop node for optical packet-switched networks.

We have demonstrated all-optical packet add-drop for all-optical packet-switched networks. Intelligent all-optical add-drop of packets is performed, based on all-optical processing of packet headers. The header and payload rates are 5 and 10 Gbits/s, respectively.
