Grover A. Swartzlander, Jr., Raul I. Hernandez-Aranda
TL;DR
This paper investigates the properties of partially coherent optical vortices, revealing non-quantized circulation and excess circulation effects, and proposes a novel vortex stellar interferometer based on these insights.
Contribution
It introduces the concept of non-quantized circulation in partially coherent optical vortices and proposes a new vortex stellar interferometer.
Findings
Circulation in partially coherent vortices is not quantized.
Excess circulation is predicted due to wave nature.
A vortex stellar interferometer is proposed.
Abstract
Rankine vortex charateristics of a partially coherent optical vortex are explored using classical and physical optics. Unlike a perfectly coherent vortex mode, the circulation is not quantized. Excess circulation is predicted owing to the wave nature of the composite vortex fields. Based on these findings we propose a vortex stellar interferometer.
