250-Gb/s self-clocked optical TDM with a polarization-multiplexed clock

In this paper we report the first demonstration of all-optical time demultiplexing at 250 Gb / s with self-clocking using polarization multiplexing of the clock and data. To achieve such high speed, an ultra high-speed device known as the Teruhertz Optical Asymmetric Demultiplexer (TOAD) is used. We also demonstrate self-clocked address recognition and routing control of a photonic switch at 250 Gb / s. The bit-error rate at the switch output was measured to be less than 10 -9 .
