Refractive index sensing using analytical calculation of angular momentum sidebands of a Laguerre Gaussian beam reflected from a plasmonic structure
Abstract When a Laguerre Gaussian beam carrying orbital angular momentum (OAM) with a specific topological charge (TC) is incident onto an interface, the reflected beam will be a superposition of different OAM states. In this study, we analytically calculate the OAM spectrum of the reflected beam fr...
