We demonstrate Si microring resonator crossbar array as a programmable nanophotonic processor. By using multi-wavelength optical signal and monolithically integrated Ge photodetectors, we performed multiply-accumulate operation for optical neural network. We demonstrated classification task for Iris dataset, resulting in prediction accuracy of 91%.
