Comprehensive thermal crosstalk model of meshed MZI topologies for neuromorphic computing

We propose a comprehensive Mach-Zehnder Interferometer (MZI) model that takes into account propagation effects, losses, thermal and optical crosstalk, and can be used to simulate the behavior of meshed MZI topologies (e.g., in the context of neuromorphic photonic computing). The model is validated by comparing the simulated results with power and spectral measurements of a 3x3 Silicon Photonic circuit based on cascaded MZIs. This circuit can be used as a programmable logic gate and this application is demonstrated with the proposed model.
