Directly measuring mode purity of single component in superposed optical vortices
Chen Wang, Yuan Ren
Mode purity is an important reference for the quality of the optical vortex. In this work, we propose a self-interference method to directly measure single component in superposed…
Measurement and Shaping of Circular Airy Vortex via Cross Phase
Chen Wang, Yuan Ren
We apply the CP to CAVs for the first time experimentally. Firstly, we introduce the propagation properties of a CAV with the LOCP in the process of measuring TCs, and measure the…
Generation and Measurement of High-order Optical Vortex via Cross-Phase
Chen Wang, Yuan Ren, Tong Liu +4
The generation and measurement of optical vortex (OV) are the basis for a variety of related applications. However, the special case of high-order OVs has not been sufficient addre…
Excitation of exciton-polariton vortices in pillar microcavities by a Gaussian beam
A. S. Abdalla, Bingsuo Zou, Yuan Ren +2
With coupled Gross-Piteavskii equations we study excitation of exciton-polariton vortices and antivortices in a pillar microcavity by a Gaussian pump beam. The structure of vortice…
