چکیده
Abstract We propose a new kind of compound optical vortex (COV) generator in this paper. The device consists an inner spiral phase plate (SPP) and outer annular plate. There is opaque band between two SPPs. Under the flat-top beam irradiation, concentric multi-ring COV rings with different topological charges radial radii can be generated. theoretical analysis lays foundation for design generator, simulation results prove effectiveness design. unique characteristics are discussed some its potential application scenarios presented. This work provides method generating using SPPs, advanced structure help to expand scope utilization tweezers, communication other fields.

متن کاملCharacteristics of Optical Interconnection for Power Transmission Based on Phase Conjugation Generation by a Ring-Resonator
To establish an interconnection for power transmission between two moving objects, optical phase conjugation is applied for non-mechanical, all-optical tracking and compensation of atmospheric distortions. The installation of the connection starts in sending a coherent pilot signal by the power receiver towards the transmitter. There, the incident light is collected and directed into a nonlinea...
متن کاملHighly intense monocycle terahertz vortex generation by utilizing a Tsurupica spiral phase plate
Optical vortex, possessing an annular intensity profile and an orbital angular momentum (characterized by an integer termed a topological charge) associated with a helical wavefront, has attracted great attention for diverse applications due to its unique properties. In particular for terahertz (THz) frequency range, several approaches for THz vortex generation, including molded phase plates co...
