摘要

我们介绍了一种基于空间调制光波形在二次谐波非线性晶体中的非线性相互作用的光学推理平台。通过调整相位匹配条件，既能实现一般全光学计算所需的高效非线性，又能优化系统性能，使其与待处理输入数据的光谱分布相匹配。

Optical inference using nonlinear optical diffraction

We present an optical inference platform based on the nonlinear interaction of a spatially modulated optical waveform in a second-harmonic-generation nonlinear crystal. Tuning the phase-matching condition allows for both efficient nonlinearity, required for general all-optical computing, and for optimizing the system performance, matching it to the spectral distribution of the input data to be processed.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
