Thermal Crosstalk Modelling and Compensation Methods for Programmable Photonic Integrated Circuits

arXiv:2404.10589v1 Announce Type: cross
Abstract: Photonic integrated circuits play an important role in the field of optical computing, promising faster and more energy-efficient operations compared to their digital counterparts. This advantage stems from the inherent suitability of optical signals to carry out matrix multiplication. However, even deterministic phenomena such as thermal crosstalk make precise programming of photonic chips a challenging task. Here, we train and experimentally evaluate three models incorporating varying degrees of physics intuition to predict the effect of …
