Speckle-based measurement of the fractional azimuthal index of orbital angular momentum beams for refractive index sensing
Abstract Light beams possessing orbital angular momentum (OAM) have gained significant interest in areas such as optical manipulation, quantum entanglement, and super-resolved imaging. The OAM per photon of such beams, typically Laguerre-Gaussian beams, is directly proportional to the azimuthal inde...
