In this paper, a novel microring resonator (MRR)-assisted Mach-Zehnder interferometric (MZI) structure to operate as an electro-optic half adder utilizing the optical switching phenomenon of Si-MRR is proposed. The proposed device has two Si-MRRs with dual inputs, used in the tandem configuration in the lower and upper arms of an MZI structure. An externally controllable optical 'π' phase shifter is also incorporated in one of the arms of the MZI. The carrier-injected forward-biased PIN waveguide structure is incorporated into the ring resonator architecture to achieve the extinction ratio (ER) tunability. For the proposed electro-optic adder, -1.85 V and +2 V are considered as logic 0 and 1, respectively. One of the output terminals will emulate an optical AND gate providing the carry bit (CB), while the other output terminal will emulate an optical EX-OR gate offering the sum bit (SB). The proposed device was modeled and simulated using MATLAB. The simulation results estimate the simulated static ER of the SB and CB is 27.44 dB and 18.08 dB, respectively. To demonstrate the proposed device's efficacy, two 10 Gb/s PRBS input streams at 1550 nm Electro-Optic Half Adder were used, and the time domain simulation results indicate a successful electro-optic half adder suitable for photonic integrated circuits (PICs).

In this article, an optical majority/minority circuit has been designed using four electro‐optic Mach‐Zehnder interferometers. The binary decision diagram (BDD) is used to optimize the Boolean logical expression. In this design we get two outputs, one performs majority logic and the other performs minority logic simultaneously. Numerical simulation has been done with the obtained data from the beam propagation method. Pseudo‐eye diagram is also plotted to find amplitude modulation (AM) and extinction ratio (ER). AM and ER are found nearly 0.4 and 13 dB, respectively. A new parameter, the optical circuit complexity factor (OCC) factor has been calculated and from the result, it has been shown that the proposed design is more optimized than other majority/minority gate designs so far.
