Optical Torque Exerted on a Rotator under Illumination of a Vortex Beam
Optical Torque Exerted Rotator Illumination Vortex Beam
2013/7/3
We investigate the torque on a specially shaped rotator produced by a vortex beam. The formulas for the torque alongx, yandzdirections are derived, and numerically calculation is performed. It is foun...
Hybrid-effect transmission enhancement induced by oblique illumination in nano-ridge waveguide
2011/11/24
In a nano-ridge waveguide under oblique illumination, we demonstrated transmission enhancement resulting from a hybrid effect between propagation modes and surface plasmon wave. The measured near-fiel...
