The possibilities and limitations of using nonlinearities in periodically poled lithium-niobate waveguides for ultrafast all-optical processing are experimentally investigated. A combination of the sum-/difference-frequency generation and pump depletion effect are exploited to obtain optical demultiplexing, add/drop multiplexing, and wavelength conversion of up to 320 Gbits/s.
