We demonstrate an all-optical XOR logic function for 40Gb/s differential phase-shift keyed
(DPSK) data signals in the C-band, based on four-wave mixing (FWM) in a silicon nanowire …

With the increasing flow of information, data rate is increasing very rapidly. This has resulted
in increased amount of heat dissipation from the processing nodes. Generally electronic …

We demonstrate the compact all-optical logic XOR and OR gates in subwavelength
plasmonic metal–insulator–metal waveguides with slot cavity resonators, especially for …

Progress in developing photonic chip based optical processing devices with ultrahigh‐
