Broadband polarization rotator with tunable rotation angle composed of three wave-plates

TL;DR

This paper presents a simple, experimentally verified broadband polarization rotator using three wave-plates, including a full-wave plate, with tunable rotation angle and dispersion compensation inspired by composite pulses.

Contribution

It introduces a novel broadband polarization rotator design with tunable angle using only three wave-plates, including a full-wave plate, with dispersion compensation.

Findings

Successfully verified experimentally the broadband rotator design.

Achieved tunable rotation angle with dispersion compensation.

Demonstrated robustness against wave-plate dispersion effects.

Abstract

A simple scheme for a broadband polarization rotator with tunable rotation angle is proposed and verified experimentally. The rotator consists of only three wave-plates, one of which is a full-wave plate. The robust approach inspired by the composite pulses analogy allows to compensate the wave-plate dispersion in large extent.
