Intelligent optoelectronic processor for orbital angular momentum spectrum measurement
Hao Wang, Ziyu Zhan, Futai Hu +4
Orbital angular momentum (OAM) detection underpins almost all aspects of vortex beams' advances such as communication and quantum analogy. Conventional schemes are frustrated by lo…
Deep-learning-based recognition of multi-singularity structured light
Hao Wang, Xilin Yang, Zeqi Liu +8
Structured light with customized complex topological pattern inspires diverse classical and quantum investigations underpinned by accurate detection techniques. However, the curren…
Guided mode meta-optics: Metasurface-dressed nanophotonic waveguides for arbitrary designer mode couplers and on-chip OAM emitters with configurable topological charge
Yuan Meng, Tiantian He, Zhoutian Liu +4
Metasurfaces have achieved fruitful results in tailoring complexing light fields in free space. However, a systematic investigation on applying the concept of meta-optics to comple…
Ultrafast two-photon emission in a doped semiconductor thin film
Futai Hu, Liu Li, Yuan Liu +3
As a high-order quantum transition, two-photon emission has an extremely low occurrence rate compared to one-photon emission, thus having been considered a forbidden process. Here,…
Estimating Granger Causality with Unobserved Confounders via Deep Latent-Variable Recurrent Neural Network
Yuan Meng
Granger causality analysis, as one of the most popular time series causality methods, has been widely used in the economics, neuroscience. However, unobserved confounders is a fund…
Hybrid topological evolution of multi-singularity vortex beams: Generalized nature for helical-Ince-Gaussian and Hermite-Laguerre-Gaussian modes
Yijie Shen, Yuan Meng, Xing Fu +1
A generalized family of scalar structured Gaussian modes including helical-Ince--Gaussian (HIG) and Hermite--Laguerre--Gaussian (HLG) beams is presented with physical insight upon…
Polygonal vortex beams in quasi-frequency-degenerate states
Yijie Shen, Zhensong Wan, Yuan Meng +2
We originally demonstrate the vortex beams with patterns of closed polygons [namely polygonal vortex beams (PVBs)] generated by a quasi-frequency-degenerate (QFD) Yb:CALGO laser re…
