320-to-10 Gbit/s all-optical demultiplexing using sum-frequency generation in PPLN waveguide

A 320-to-10 Gbit/s all-optical demultiplexer based on sum-frequency generation in a periodically-poled lithium niobate (PPLN) waveguide is demonstrated. A bit-error-rate of 10 -9 is achieved with a power penalty of 1.5 dB.
