Generating Circularly Polarized Light Using Hybrid Near‐Zero and High‐Index Materials

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A flat‐optics approach to manipulating the polarization state of light is proposed using evanescent‐wave interactions in hybrid epsilon‐near‐zero and high‐index materials. The design enables linear‐to‐circular polarization conversion in a wavelength‐scale device design without depending on patterning or bulky optics and operates in both reflection and ...

Evolution and Conceptual Insights into the Geometric Phase of Light: A Comprehensive Review

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This review presents a unified account of the geometric phase of light, linking its fundamental principles to diverse manifestations in polarization, spatial, and vector modes. By connecting theoretical frameworks with key experimental realizations, it reveals a coherent physical picture that deepens understanding and stimulates new directions in ...

Broadband Reflective Terahertz Quarter‐Wave Metasurface Enabled by Two‐Photon Polymerization 3D‐Printing

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A compact reflective terahertz quarter‐wave metasurface fabricated via 2PP‐3D printing method is experimentally demonstrated near 1 THz frequency. Broadband linear‐to‐circular polarization conversion is achieved over 0.75–1.30 THz (∼54% fractional bandwidth), with axial ratio below 3 dB and ellipticity approaching −1.
