“…In 2021, FWM nonlinearity of PhC-SOA was used in the design and simulation of an all-optical AND gate. 9 In this design, no CW signal was used to carry out intended logic output. Various nonlinear features including carrier heating, carrier depletion, and spectral hole burning of PhC-SOA were considered to simulate the structure numerically.…”

Future communication networks require the entire communication system to be all-optical to overcome the bandwidth constraints of electronics. All-optical devices play a vital role in supporting future networks, which demand a high speed of up to Tbps. An all-optical gray code converter operation was demonstrated numerically using a photonic crystal semiconductor optical amplifier (PhC-SOA) in a Mach-Zehnder interferometric (MZI) configuration at 1 Tbps for M-ary differential phase shift keying modulated binary and BCD inputs. The design achieved a very high extinction ratio of about 123.8 dB with a good quality factor value of about 45. The results show that PhC-SOA-based XOR and OR gates in the gray code converter design exhibits improved modulation features compared with traditional SOAs in our previous works.

“…At present, scholars have proposed some schemes to implement optical logic gate and conducted relevant experimental verification, which are roughly divided into two categories: schemes based on optical media and those based on modulators. In the former scheme, semiconductor optical amplifier (SOA) [10]- [12], Highly nonlinear fiber (HNLF) [13]- [14], silicon nanowire [15], periodically poled lithium niobate (PPLN) [16] and silicon waveguide [17] are widely used. However, SOA is susceptible to carrier recovery time, is more sensitive to polarization, and is short in terms of speed limit and delay.…”

In this work, we employ two Mach-Zehnder modulators (MZM) to achieve a novel six kinds of reconfigurable optical logic gate in millimeter wave over fiber, in which one MZM is used to generate millimeter wave (mm-wave) signal and the other is used to attain optical logic gate. By adjusting the direct current (DC) bias voltage of the first MZM, a frequency doubling mm-wave signal can be obtained and no filter is needed. By controlling the radio frequency (RF) drive voltage and DC bias voltage of the second MZM, the phase of between upper and lower arms can be converted. By adjusting the phase of the first channel RF signal to ( / 2, 0)  , setting the phase of the second channel RF signal to (0, / 2)  and controlling the bias voltage to let the phase of the upper and lower to be /2  and /4  , respectively, OR logic gate can be obtained. To obtain AND, NOR, NAND, XOR and NXOR logic gate, we just need to get proper phase by adjusting the RF drive voltage and DC bias voltage of the second MZM. According to the simulation, the millimeter wave signal with a frequency of 50 GHz can be obtained, which has completed the logic operation.

A Janus Logic Gate with Sensing Function

A layered metastructure (LM) formed by a quasi-periodic arrangement of graphene and isotropic dielectric mediums, which can realize the functions of the tunable logic gate and refractive index (RI) sensing based on spin Hall effect (SHE), is theoretically studied. The asymmetric arrangement of the mediums and the increased angle of the incident electromagnetic waves (EWs) equip the LM with Janus feature. Through the modulation of the graphene chemical potential, the sharp absorption peak (AP) in the terahertz (THz) range can be obtained, and then the AP can be used to implement NOT logic and OR logic respectively corresponding to the forward and backward scales. By locating the incident angle of light corresponding to the SHE displacement peak, the linear measurement relationship between RI and SHE angle can be realized, and the widest RI measurement range is 1-1.4 with the angles changing from 21.88°to 61.84°. Additionally, a good linear range can be achieved, owning the optimum sensitivity (S) up to 153.5°RIU −1 . The RI sensing still strictly follows the logic functions of the forward NOT and backward OR via adjusting the chemical potential of graphene and discriminating the peak value of SHE displacement.
