Radiation of Optical Angular Momentum by a Dipole Source inside a Magneto-optical Environment

TL;DR

This paper demonstrates that a magneto-optical environment can induce angular momentum radiation from an unpolarized dipole source, enhanced by Purcell effects, revealing new ways to control electromagnetic radiation.

Contribution

It introduces the novel concept that a magneto-optical environment can generate angular momentum radiation from an unpolarized dipole, with Purcell-enhancement effects.

Findings

Magneto-optical environment induces angular momentum radiation.

Purcell-enhancement boosts the radiation.

Unpolarized dipole sources can emit angular momentum.

Abstract

Radiation of electromagnetic energy by electric or magnetic multipole sources can be modified by their local environment. In this work we demonstrate that a magneto-optical environment of an unpolarized dipole source induces the radiation of angular momentum into space. This radiation benefits from Purcell-enhancement.
