Simulation study demonstrates optical SR latch operation at 30 Gbps using vertical PN junction micro-ring resonators, highlighting their utility in high-speed optical logic circuits.
We present the design and simulation of optical SR NAND and SR NOR latches using two vertical PN junction micro-ring resonators. By varying the doping concentrations and applied reverse voltages, the functionality of the latches is achieved. The proposed designs are analyzed theoretically and validated through simulations which demonstrate static and dynamic responses with data rates up to 30 Gbps. These results highlight the potential of vertical PN junction micro-ring resonators for high-speed optical logic circuits.
