Extended Data Fig. 10: Photonic disclination cavities for various topological charges and polarization states.
From: Vortex nanolaser based on a photonic disclination cavity
Our design strategy is used to generate resonant modes with |q| = 2 or radial polarization. a, C6 symmetric hole-type photonic disclination cavity (Fig. 2i). The colored region represents the dielectric material with a refractive index of 3.33. b, Optical vortex mode excited in the cavity of a. The Hz field (left), polarization vector field (upper right), and phase distribution (lower right) are calculated, showing the vortex feature of |q| = 2. c, C5 symmetric rod-type photonic disclination cavity. The colored region represents the dielectric material with a refractive index of 3.33. d, Radial polarization mode excited in the cavity of c. The Ez field (left), polarization vector field (upper right), and phase distribution (lower right) are calculated.
