Figure 3
(a) Examples of waveforms processed during the XOR task. The pump laser driving the input port of the MR is shown in black, while the pump and probe outputs from the Drop port are respectively shown in red and blue. (b) Bit Error Rate (BER) as a function of the bitrate for the 1-bit delayed XOR task. Black dots use a predictor matrix \({\mathbf {X}}\) whose entries are sampled from the input pump power. Red and blue dots use respectively predictors sampled from the pump and the probe traces at the Drop port of the MR. In all the three cases, the average pump power is set to \(3\,{\text {dBm}}\). (c) Bit Error Rate as a function of the average pump power for a fixed bitrate of \(20\,{\text {Mbps}}\). The insets show details of the probe waveform at the pump powers \(-10\,{\text {dBm}}\) and \(4\,{\text {dBm}}\).
