Abstract:
Internal conical refraction (ICR) transforms a ray incident upon the optic axis of a biaxial crystal into a cone of light within the medium and a hollow cylinder of light upon exiting. If the incident ray is circularly polarised each of the electric field components is
separated out forming a π rotation of linear polarisation around the ring. The phenomenon
of ICR has recently been expanded to incorporate paraxial diffraction of the conical beam
(ICD). The paraxial transformation of a Gaussian beam results in the radial electric field of
the conical beam described as a superposition of Bessel functions of zero- and first-order.
