Abstract
We propose a comprehensive Mach-Zehnder Interferomenter (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 it can be shown to implement the weighted sum of the linear portion of an artificial neuron. Both applications are demonstrated with the proposed model.
