A 7×4 Silicon Photonic Reconfigurable Optical Analog Processor with Algorithmic Calibration

This work presents a large-scale 7x4 square optical mesh-based programmable analog optical processor, or optical FPGA, fabricated in a standard CMOS-compatible foundry. The processor employs an electronic backend with optimized on-chip monitors and microheaters for algorithmic calibration for the automatic configuration of optical circuits.
