Ultrafast optical demultiplexers capable of switching a user channel from data streams as high as hundreds of GHz are essential components in high speed optical time division multiplexed networks and optical signal processing. Terahertz optical asymmetric demultiplexers (TOAD) utilize interferometric configurations to explore these large and slow nonlinearities in semiconductor optical amplifiers (SOA). Switching windows of a few picoseconds are achieved eventhough the recovery time of the SOAs is fairly long, on the order of a few hundred picoseconds. The width and position of the switching window depends on the placement to the SOA and carrier dynamics.
