Laguerre-Gaussian transform for rotating image processing
Dan Wei, Jiantao Ma, Tianxin Wang +8
Rotation is a common motional form in nature, existing from atoms and molecules, industrial turbines to astronomical objects. However, it still lacks an efficient and reliable meth…
Generations of high efficiency, high purity, and broadband Laguerre-Gaussian modes from a Janus optical parametric oscillator
Dunzhao Wei, Pengcheng Chen, Xiaopeng Hu +7
Laguerre-Gaussian (LG) modes, carrying orbital angular momentum of light, are critical for important applications such as high-capacity optical communications, super-resolution ima…
Generating controllable Laguerre-Gaussian laser modes through intracavity spin-orbital angular momentum conversion of light
Dunzhao Wei, Yue Cheng, Rui Ni +4
The rapid developments in orbital-angular-momentum-carrying Laguerre-Gaussian (LG0 l) modes in recent years have facilitated progresses in optical communication, micromanipulation…
Nondestructive on-chip detection of optical orbital angular momentum through a single plasmonic nanohole
Dunzhao Wei, Yongmei Wang, Dongmei Liu +5
Optical orbital angular momentum (OAM) provides an additional dimension for photons to carry information in high-capacity optical communication. Although the practical needs have i…
Coupled orbital angular momentum conversions in a quasi-periodically poled LiTaO3 crystal
Xinyuan Fang, Guang Yang, Dunzhao Wei +8
We experimentally demonstrate the orbital angular momentum (OAM) conversion by the coupled nonlinear optical processes in a quasi-periodically poled LiTaO3 crystal. In such crystal…
Diffraction Interference Induced Superfocusing in Nonlinear Talbot Effect
Dongmei Liu, Yong Zhang, Jianming Wen +6
We report a simple, novel sub-diffraction method, i.e. diffraction interference induced super-focusing in second-harmonic (SH) Talbot effect, to achieve focusing size of less than…
