Miniature polarimeter with curved hyperbolic metamaterials

Abstract

The capability of curved hyperbolic metamaterials to guide the emission of a dipole-emitter into two separate channels depending on the emission helicity with high confinement provides new possibilities for polarization detection. In this work, we numerically demonstrate a novel design of miniature Stokes polarimeter using hyperbolic metamaterial structure coupled with two dipole-emitters. Through determining the four intensity signals arising from the two directional radiation channels of each dipole-emitter, the state of polarization of the incident photons can be analyzed. Numerical simulations also demonstrated that such a design is capable of working with a bandwidth of at least 40 nm. Such a compact full Stokes parameter polarimeter could be a potential candidate for high spatial resolution polarization sensor and imager for a wide variety of applications.
