Photonic spin and orbital angular momenta, which are determined by the polarization and
spatial degrees of freedom of photons, are strongly coupled with each other in …

Dielectric metasurfaces have achieved great success in realizing high-efficiency wavefront
control in the optical and infrared ranges. Here, we experimentally demonstrate several …

The zebrafish, a model organism for which a plethora of molecular and genetic techniques
exists, has a lifelong replacing dentition of 22 pharyngeal teeth. This is in contrast to the …

In this paper, a new method is proposed to generate self-image three-dimensional (3-D)
optical bottle beam (OBB) by focusing non-diffracting Bessel beam using an axicon. The …

Frozen waves (FWs) are a class of diffraction-and attenuation-resistant beams whose
intensity pattern along the direction of propagation can be chosen arbitrarily, thus making …

In this paper, the zero-order Bessel beam at W band is generated by using a diagonal horn,
a convex lens, and an axicon. The generated Bessel beam has a beam spot size of 5.5 mm …

We present an intuitive and versatile method that can dynamically generate 2D and 3D
tailored light patterns. The light structures are generated by dynamically implementing …

摘要理论分析和实验研究了光源相干度对其产生的Bessel 光最大无衍射距离的影响. 以He-Ne
激光器为光源, 用旋转毛玻璃法产生部分相干光, 经过扩束后再用轴棱锥法产生Bessel 光束 …

Scattering of a 1D Airy beam light sheet by a chiral sphere is numerically studied within Mie
theory and the plane-wave spectrum method. To testify to the validity of our code and …

Superposition of a Bessel beam with another beam was usually achieved using an Axicon
or a SLM. Here we demonstrate a straightforward but powerful method to superpose a …
