“…20 An optical logic operation scheme utilizing cross gain modulation (XGM) and four-wave mixing (FWM) effects in SOA was proposed, and the logic function with a speed of 160 Gbit/s was realized on the simulation platform. 21 The research team of Tsinghua University realized 100 Gbit/s all-optical NOR, OR, and other logic operations with an SOA and optical filtering in the experiments. By deploying or not deploying continuous wave (CW) light at the input of SOA and adjusting the tunable optical band-pass filter (OBPF) at the output of SOA, logic can be easily reconfigured.…”

We proposed a new and simple scheme to implement exclusive OR (XOR) and not exclusive OR (NXOR) logic operations in the optical domain enabled by a dual-parallel phase modulator (PM). Both the intensity and phase of the optical signal are utilized to represent the four different states of two binary inputs, and direct detection is used to map the four states to the corresponding binary output. Through numerical analysis, two PMs with phase offsets were adjusted to π∕2, and the phase shifter between the two PMs was controlled atπ∕2; thus, the NXOR logic gate was successfully carried out. Two PMs with phase offsets were adjusted to π∕2, and the phase shifter between the two PMs was controlled atπ; thus, the XOR logic gate was successfully carried out. Simulations were successfully carried out at the speed of 10 Gb/s.

“…Such optical component has attracted considerable attention in recent researches [2][3][4][5]7,[19][20][21][22][23][24][25][26][27][28][29][30][34][35][36] assisting the study fields and research lines aforementioned, as well as other additional lines of research. A nonlinear Sagnac interferometer is a very stable and extremely versatile optical component, which was initially proposed by Doran act as a "bit" of fundamental datum in ultra-fast optical processes [2,3].…”
