160 Gb/s all-optical signal processing is demonstrated exploiting pump depletion in addition to sum and difference frequency generation (SFG/DFG) in a single Periodically Poled Lithium-Niobate (PPLN) waveguide. 160 Gb/s time-domain extraction and insertion operations of channels are obtained in an Optical Time Division Multiplexing (OTDM) system. Moreover, 160 Gb/s digital operations including half-adder, half-subtracter and AND/OR/XOR functions are carried out. The use of pump depletion effect allows to process ultrafast signals due to its high efficiency and ultrafast dynamics. 160 Gb/s Bit Error Rate (BER) measurements confirm the effectiveness of all presented functionalities.
