Abstract
Guided waves are the perfect carriers of electromagnetic signals in planar miniaturized devices due to their high localization and controlled propagation direction. However, it is still a challenge to control the polarization of propagating guided waves. In this work, the broadband polarization TE-TM degeneracy of highly localized guided waves propagating along an all-dielectric metasurface and a subwavelength chain of dielectric high-index cylinders is discovered, both theoretically and experimentally. Using the discovered near-field polarization degree of freedom, the polarization transformation for guided waves propagating along a subwavelength chain of dielectric cylinders at any frequency within the finite spectral range is demonstrated experimentally. Namely, the simplest planar near-field polarization device – the quarter-wave-retardation (linear-to-circular) polarization transformer of guided waves is implemented. The results obtained discover the polarization degree of freedom for guided waves paving the way toward numerous applications in flat optics and planar photonics.
