Abstract

A polarization rotator is designed and fabricated to rotate the polarization direction of an electromagnetic wave to an arbitrary angle. The device employs a mirror-symmetric, paired periscopic architecture composed entirely of reflective elements, which enables operation over a broad wavelength range. Linearly polarized lasers spanning the visible, near-infrared, and mid-infrared regions are used to validate its broadband compatibility and high orientational accuracy. Extinction-ratio measurements confirm effective preservation of polarization, meeting the requirements of most optical applications.
