Generation and shaping of near-field optical vortices using plasmonic spiral and slot
碩士 === 國立清華大學 === 光電工程研究所 === 100 === In this work, we use finite-difference time-domain method to simulate the optical vortex phenomenon of surface plasmons. An optical vortex is characterized by its topological charge, which denotes the number of phase singularities within a 2 azimuthal rotatio...
