Spawning rings of exceptional points out of Dirac cones
Bo Zhen, Chia Wei Hsu, Yuichi Igarashi +6
The Dirac cone underlies many unique electronic properties of graphene and topological insulators, and its band structure--two conical bands touching at a single point--has also be…

Fast switchable electro-optic radial polarization retarder
B. C. Lim, P. B. Phua, W. J. Lai +1
A fast, switchable electro-optic radial polarization retarder (EO-RPR) fabricated using the electro-optic ceramic PMN-PT is presented. This EO-RPR is useful for fast, switchable ge…

Ultra-Broadband Radial Polarization Conversion based on Goos-Hanchen Shift
P. B. Phua, W. J. Lai
We demonstrate, for the first time, a scheme that generates radially-polarized light using Goos-Hanchen shift of a cylindrically symmetric Total Internal Reflection. It allows ultr…
