Unitary optical processors (UOPs) are task-specific computing units that can ultimately enable ultrafast and energy-efficient unitary matrix-vector multiplications based on the interference between coherent optical beams. The UOP using multiport directional couplers (MDCs) holds great promise in large-scale integration because of its unique robustness against fabrication errors. Here, we demonstrate a 10-port robust UOP on a silicon photonic chip, which is so far the largest-scale UOP using multiport directional couplers. We further show the unique flexibility of this architecture by demonstrating operations for both the transverse electric (TE) and the transverse magnetic (TM) polarizations, which has never been realized in previous UOPs. This flexible and robust architecture is suitable for various scenarios in deep learning, optical communication, and quantum information processing.

硅光子芯片上的十端口单一光处理器

幺正光学处理器 (UOP) 是特定于任务的计算单元,最终可以基于相干光束之间的干涉实现超快速和高能效的酉矩阵向量乘法。使用多端口定向耦合器 (MDC) 的 UOP 因其独特的抗制造错误鲁棒性而在大规模集成中具有广阔的前景。在这里,我们展示了硅光子芯片上的 10 端口稳健 UOP,这是迄今为止使用多端口定向耦合器的最大规模 UOP。我们通过演示横向电 (TE) 和横向磁 (TM) 极化的操作进一步展示了这种架构的独特灵活性,这在以前的 UOP 中从未实现过。这种灵活而健壮的架构适用于深度学习中的各种场景,
