Unidirectional focusing of light using structured diffractive surfaces
Yuhang Li, Tianyi Gan, Jingxi Li +2
Unidirectional optical systems enable selective control of light through asymmetric processing of radiation, effectively transmitting light in one direction while blocking unwanted…
Optical Generative Models
Shiqi Chen, Yuhang Li, Hanlong Chen +1
Generative models cover various application areas, including image, video and music synthesis, natural language processing, and molecular design, among many others. As digital gene…
Lying mirror using structured surfaces
Yuhang Li, Shiqi Chen, Bijie Bai +1
We introduce an all-optical system, termed the "lying mirror", to hide input information by transforming it into misleading, ordinary-looking patterns that effectively camouflage t…
Unidirectional imaging with partially coherent light
Guangdong Ma, Che-Yung Shen, Jingxi Li +8
Unidirectional imagers form images of input objects only in one direction, e.g., from field-of-view (FOV) A to FOV B, while blocking the image formation in the reverse direction, f…
Optimizing Structured Surfaces for Diffractive Waveguides
Yuntian Wang, Yuhang Li, Tianyi Gan +3
Waveguide design is crucial in developing efficient light delivery systems, requiring meticulous material selection, precise manufacturing, and rigorous performance optimization, i…
Training of Physical Neural Networks
Ali Momeni, Babak Rahmani, Benjamin Scellier +25
Physical neural networks (PNNs) are a class of neural-like networks that leverage the properties of physical systems to perform computation. While PNNs are so far a niche research…
Multiplane Quantitative Phase Imaging Using a Wavelength-Multiplexed Diffractive Optical Processor
Che-Yung Shen, Jingxi Li, Tianyi Gan +4
Quantitative phase imaging (QPI) is a label-free technique that provides optical path length information for transparent specimens, finding utility in biology, materials science, a…
Multiplexed all-optical permutation operations using a reconfigurable diffractive optical network
Guangdong Ma, Xilin Yang, Bijie Bai +8
Large-scale and high-dimensional permutation operations are important for various applications in e.g., telecommunications and encryption. Here, we demonstrate the use of all-optic…
All-optical complex field imaging using diffractive processors
Jingxi Li, Yuhang Li, Tianyi Gan +3
Complex field imaging, which captures both the amplitude and phase information of input optical fields or objects, can offer rich structural insights into samples, such as their ab…
Subwavelength Imaging using a Solid-Immersion Diffractive Optical Processor
Jingtian Hu, Kun Liao, Niyazi Ulas Dinc +14
Phase imaging is widely used in biomedical imaging, sensing, and material characterization, among other fields. However, direct imaging of phase objects with subwavelength resoluti…
Information hiding cameras: optical concealment of object information into ordinary images
Bijie Bai, Ryan Lee, Yuhang Li +4
Data protection methods like cryptography, despite being effective, inadvertently signal the presence of secret communication, thereby drawing undue attention. Here, we introduce a…
