Optics communications, 1996•ElsevierA spiral phaseplate is used at millimetre-wave frequencies to transform a free-space,
fundamental Hermite-Gaussian mode into a Laguerre-Gaussian mode with an azimuthal
phase component. A ray optics analysis confirms that the Laguerre-Gaussian beam
produced has a total angular momentum equivalent to ℓħ per photon.
