Experimental results demonstrate a 99.47% fidelity in a 6x6 coherent crossbar architecture, highlighting a new calibration algorithm.
We demonstrate an on-chip 6x6 MZI-based coherent crossbar architecture and provide a calibration algorithm based on the creation of interferometric structures. Experimental results over 5000 matrices show a fidelity of 99.47±0.14%.
