High-Speed Optical Binary Neural Network Accelerator Enabled by Nonvolatile MEMS Phase Shifters for Edge AI Applications
Bibliographic record
Abstract
This paper presents a novel approach for implementing Binary Neural Networks (BNNs) utilizing nonvolatile optical phase shifters. These phase shifters employ a micro-electromechanical system (MEMS) tuning mechanism, which enables the adjustment of the refractive index and phase of the propagating mode. In this approach, the weights of the BNN can be controlled by applying electrical signals to the phase shifters. Moreover, due to the nonvolatile operation of these devices, the network’s weights remain stable even when the electrical power source is cut off. The phases of the propagating modes, manipulated by the proposed phase shifters, determine the logic of the photonic circuit. The in-memory design of this device eliminates the need for network register banks, thereby significantly reducing resource usage, footprint, and power consumption. This approach offers much faster operation than other technologies, such as CMOS or spintronics, making it particularly appealing for edge artificial intelligence applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
