Oblique rotational axis detection using elliptical optical vortex based on rotational Doppler effect
Xiangyang Zhu, Yuan Ren, Yaohui Fan +6
The rotational Doppler effect (RDE) of structured light carrying orbital angular momentum (OAM) has attracted widespread attention for applications in optical sensors and OAM spect…
Single-shot spatial instability and electric control of polariton condensates at room temperature
Ying Gao, Xuekai Ma, Xiaokun Zhai +11
In planar microcavities, the transverse-electric and transverse-magnetic (TE-TM) mode splitting of cavity photons arises due to their different penetration into the Bragg mirrors a…
One-time measurement to characterize complex amplitude single component in symmetry superposed optical vortices
Chen Wang, Yuan Ren
Complex amplitude measurement is an essential prerequisite for light field characterization. In this work, we propose a one-time measurement method to characterize the complex ampl…
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 Perfect Optical Vortex via Cross Phase
Chen Wang, Yuan Ren
We investigate a method for the measurement and shaping of a perfect optical vortex (POV) by using the cross-phase for the first time. Experimentally, we propose a method to measur…

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…
A new kind of Hermite-Gaussian-like optical vortex generated by cross-phase
Chen Wang, Yuan Ren, Tong Liu +2
We propose a new kind of optical vortex called the Hermite-Gaussian-like optical vortex (HGOV) inspired by the crossphase (CP). Theoretically, we investigate how the CP is decouple…
Optical Vortex Shaping & Multiple Singularities Manipulation via High-order Cross-phase
Chen Wang, Yuan Ren, Tong Liu +3
Increasing demand for practical applications is forcing deeper research into optical vortices (OVs): from the generation and measurement to shaping and multiple singularities manip…
Exciton interaction induced spin splitting in MoS monolayer
Yao Li, G. Li, Xiaokun Zhai +11
By pumping nonresonantly a MoS monolayer at K under a circularly polarized cw laser, we observe exciton energy redshifts that break the degeneracy between B excitons with…
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…
