Photonic toroidal vortex
Chenhao Wan, Qian Cao, Jian Chen +2
Toroidal vortices are whirling disturbances rotating about a ring-shaped core while advancing in the direction normal to the ring orifice. Toroidal vortices are commonly found in n…
Generation of four-dimensional hyperentangled N00N states and beyond with photonic orbital angular momentum and detection-basis control
José César Guerra Vázquez, Emmanuel Narváez Castañeda, Roberto Ramírez Alarcón +3
Hyperentanglement of photonic light modes is a valuable resource in quantum information processing and quantum communication. Here we propose a new protocol using the interference…
Ince-Gauss Photons in Turbulent Atmosphere: Effect of quantum numbers on beam resilience
Emmanuel Narváez Castañeda, Roberto Ramírez Alarcón, José César Guerra Vázquez +3
In this work, we present an extensive analysis on the nature and performance of Ince-Gauss beams, elliptical solutions of the paraxial wave equation that have orbital angular momen…
A modal description of paraxial structured light propagation
Hend Sroor, Chane Moodley, Valeria Rodrıguez-Fajardo +2
Here we outline a description of paraxial light propagation from a modal perspective. By decomposing the initial transverse field into a spatial basis whose elements have known and…
Generation of transversely oriented optical polarization Möbius strips
Lixiu Su, Xindong Meng, Yu Xiao +2
We report a time-reversal method based on the Richards-Wolf vectorial diffraction theory to generate transversely oriented optical Möbius strips that wander around an axis perpendi…
Spin-orbit coupling within tightly focused circularly polarized spatiotemporal vortex wavepacket
Jian Chen, Lihua Yu, Chenhao Wan +1
Spin-orbital coupling and interaction as intrinsic light fields characteristics have been extensively studied. Previous studies involve the spin angular momentum (SAM) carried by c…
Experimental demonstration of cylindrical vector spatiotemporal optical vortex
Jian Chen, Chenhao Wan, Andy Chong +1
We experimentally generate cylindrically polarized wavepackets with transverse orbital angular momentum, demonstrating the coexistence of spatiotemporal optical vortex with spatial…
Photonic orbital angular momentum with controllable orientation
Chenhao Wan, Jian Chen, Andy Chong +1
Vortices are whirling disturbances commonly found in nature ranging from tremendously small scales in Bose-Einstein condensates to cosmologically colossal scales in spiral galaxies…
