We propose a two-dimensional beam scanner based on hitless microring switch array. By changing the resonance state of the microring interference between different wavelength selection switches is avoided. The operation complexity of the beam steering FPA chip based on the microring switch array is reduced.
We propose a complex-valued matrix-vector multiplication method in this work, which make full use of the amplitude and phase information of input signal light and weight matrix. We demonstrate our computing method theoretically and experimentally. In order to verify our theory, a photonic chip is designed and used to setup a photonic neural network system, and the corresponding accuracies reach more than 90%.
