160-Gb/s Optical Packet Switching Subsystem With a Monolithic Optical Phased-Array Switch

1$\,\times\,$ 8 and 1$\,\times\,$ 16 optical packet switching (OPS) node subsystems are demonstrated. The OPS node consists of a $1 \times {N}$ monolithically integrated InP optical phased-array switch, an electronic switch controller, and a label extractor/eraser that utilizes cascaded reflective fiber Bragg gratings. In-band parallel labels are employed to encode the address information. 160-Gb/s optical time-domain-multiplexed packets are dynamically switched to 8 and 16 outputs with power penalties of 0.5 and 0.7 dB, respectively.
