Demonstration of a 1024-channel time slot selector for ultrafast OTDM networks

In the paper, we demonstrate a tunable delay line which is able to access 1024 channels, each at 50 Mbps, with reconfiguration time of 20 ns allowing aggregate capacity of up to 50 Gbps. To our knowledge, this is the largest number of rapidly tuned channels achieved to date, thus demonstrating the potential of optical time division multiplexing (OTDM) for large dimensionality systems.
