Surface optical vortices [PDF]
Physical Review A, 2009 It is shown how the total internal reflection of orbital-angular-momentum-endowed light can lead to the generation of evanescent light possessing rotational properties in which the intensity distribution is firmly localized in the vicinity of the surface.

Spatiotemporal Optical Vortices [PDF]
Physical Review X, 2016 We present the first experimental evidence, supported by theory and simulation, of spatiotemporal optical vortices (STOVs). A STOV is an optical vortex with phase and energy circulation in a spatiotemporal plane.

Surface Plasmon Resonance Sensors Using Optical Vortices [PDF]
NanomaterialsThis study investigates the change in both the angular position and width of the reflectance minimum of an SPR sensor in the Kretschmann configuration when optical vortices instead of plane waves are used for illumination. An analytical expression of the
