Abstract
In this paper, we report the experimental demonstration of 320 Gb/s
demultiplexing to eight simultaneous always-on 40 Gb/s tributaries with
near-zero latency. The single-channel, single-polarization 320 Gb/s
optical-time-division-multiplexed signal was processed by a
copy-and-sample-all architecture. 1-to-8wavelength
multicasting over more than 10 THz of bandwidth was achieved in a
self-seeded two-pump parametric amplifier, and was followed by a single
gate, multicolored sampling with equalized response over more than 20 THz.
The single gate operation allows for truly scalable real-time processing
while avoiding the complexity of parallel pipelines processing. Error-free
performance was measured over all extracted 40 Gb/s tributaries with less
than 4 dB power penalty compared to conventional single tributary
gating.
