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,…
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…
