Neuromorphic photonic circuit modeling in Verilog-A
By Technical Paper Link - 19 Apr, 2022 - Comments: 0

Abstract "One of the significant challenges in neuromorphic photonic architectures is the lack of good tools to simulate large-scale photonic integrated circuits. It is crucial to perform simulations on a single platform to capture the circuit’s behavior in the presence of both optical and electrical components. Here, we adopted a Verilog-A based approach to model neuromorphic photonic cir... » read more
