Wavelength-encoded neuromorphic inference enabled by microcavity MoS2 photodetector arrays

Xiang Chen, Kangjian Di, Fuhao Yu, Jiashu Li et autres

Biological vision systems tightly couple spectral sensing with temporal integration to extract task-relevant information with minimal data movement. In contrast, conventional optoelectronic vision hardware typically separates photodetection from electronic computation, incurring substantial latency and energy costs. Optical neural networks can alleviate this …

All-Optical Wearable Gesture Sensing With a Learnable Photonic Linear Filter Bank for Near-Sensor Classification

Kangjian Di, Jiashu Li, Silin Chen, S. J. Chen et autres

Wearable gesture recognition systems typically rely on multi-channel electrical sensing followed by analog-to-digital conversion, which can incur substantial data movement, latency, and power overhead. Here, we present a photonic feature extraction neural network (PFENN), which provides an electrical-transduction-free optical sensing interface and …

Multi-domain transformer IQA algorithm for AOI optical scheme evaluation

Zikang Zeng, Yiru Wang, Jinghan Wang, Tianwu Lei et autres

Automatic Optical Inspection (AOI) systems require carefully designed optical configurations to ensure adequate defect visibility during image acquisition. In industrial practice, engineers typically compare images captured under different optical settings and manually select the configuration that best exposes defects. However, this process …

OptoChat: a large language model with retrieval augmented generation for optics

Xiaoqing Bao, Hairuo Wang, Silin Chen, Yali Zhang et autres

Abstract Large language models (LLMs) show strong performance in general text generation and knowledge-based question answering (QA). However, a substantial performance gap remains in optics, a knowledge-intensive scientific field. General-purpose LLMs, trained and tuned without sufficient optics knowledge, often hallucinate when handling …
