This code supports the FDTD simulation results presented in 2019 paper "Digital signal processing in coupled photonic crystal waveguides and its application to an all-optical AND logic gate". The paper is available online.
Main simulation script is NAND_Full_Simulation_SC.m. The file is supposed to be run top-to-bottom, in MatLab. This code simulates the entire structure. The NOT gate (left) and the AND gate (right). Simulation is CPU-only and thus slow. Alternatively a python script NAND_Full_Simulation_SC.py replicates some of the results of NAND_Full_Simulation_SC.m. See required python packages in requirements.txt
Suggested future direction of work, at least on the coding side, should focus on using GPU-acceleration of the simulation. The code is mostly a loop over 2D stencil-kernels. GPUs are well-suited for calculating these.
