Discovery of Polarization Degree of Freedom for Localized Light

Explore the discovery of polarization degree of freedom for localized light in this 33-minute HyperComplex Seminar talk. Delve into the challenges of maintaining polarization degeneracy in miniaturized and planar photonic devices, and learn about innovative solutions using nanostructured dielectric slabs and all-dielectric metasurfaces. Examine the concept of merging polarization degeneracy with high localization for guided waves, and understand the potential applications in waveguide polarizers and self-complementary metasurfaces. Investigate the excitation of TE- and TM-polarized surface waves, and discover how to achieve linear, circular, and elliptical polarizations in planar photonic devices. Gain insights into the future of polarization control in guided waves and the potential impact on next-generation planar photonic polarization devices.
