“…However, unlike electrical circuits, optical combinational logic functions are usually implemented by an entire optical switching network directly in optical DL [14], thus does not lead to delay accumulation. Various combinational DL operations have been demonstrated [73][74][75][76][77][78][79][80][81][82][83][84] and recent publications are to be introduced in this sub-section.…”

“…Considering that the MRR is a power splitter and the MMI is a power combiner in that device, the computed results always have two stages in the Sum port Y 2 . An effective method to eliminate this phenomenon is to avoid using MMI in the circuit [78]. Subsequently, a circuit was demonstrated to perform half-subtracting operation [79].…”

Optical directed logic (DL) is a novel logic operation scheme that employs electrical signals as operands to control the working states of optical switches to perform the logic functions. This review first provides an overview of the concept and working principle of DL. The developing trends of DL computing are then discussed in detail, including the fundamental optical DL gates, combinational optical DL operations, reconfigurable logic computing, low power optical logic computing, and programmable photonic network. The concluding remarks provide an outlook on the DL future development and its impacts in optical computing. Graphical Abstract

“…Silicon Photonic is believed to be a major platform to achieve great benefits in optical computing systems due to its advantages such as high refractive index, high bandwidth, high speed 3 , low power consumption, low electromagnetic interference 4 , etc. So, in Photonic Integrated Circuits (PICs), where photons are used to carry information instead of electrons, the footprint area is also critical as it affects the price for manufacturing process 5 , as well as the required power consumption 5,6 . As a result, micro-ring resonators (MRR) are mostly used as basic units for optical digital circuits in PICs due to their compactness and a higher sensitivity 7 .…”

This work proposes the design of optical SR latch. The fundamental component of the latch is a micro-ring resonator (MRR), which utilizes a plasma dispersion effect with an applied reverse bias voltage to tune its resonance wavelength. The proposed SR latch is made up of two identical micro-ring resonators with similar doped regions and the same logic mode of operation. The memory properties are realized by implementing the feedback loop between the input and output of the circuit. A time-varying simulation is carried out by applying two pseudorandom electrical input signals S and R into the circuit at a data rate of 25 Gbps. The work concludes with a comparative analysis between two optical SR latches (NOR-based and NAND-based).

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).
