All-optical XOR-, OR-, NOT-, and AND-gate were demonstrated for 10 Gb/s return-to-zero on-off keying (RZ-OOK) signals using a single experimental setup. This setup can be set to output different logic by altering input power, state-of-polarization, center frequencies of input optical signals, and/or input bitstreams. Full-width at half-maximum pulsewidth of the input and the output signals were less than 5.1 ps in all cases showing a possibility of higher data rate operation at 80Gb/s or beyond.
