Time and wavelength domain contention resolution in an optical packet routing node

We experimentally demonstrate an optical packet routing node with contention resolution in the time and wavelength contention domain. The node comprises an optical buffer and a wavelength converter. Although the experimental results are shown at 10 Gb/s, the bitrate can be increased substantially. Bit-error rate measurements are shown, sustaining only 3.5 dB power penalty after 10 µs of optical buffering and wavelength conversion over 5 nm wavelength span.
