In this work, we study the potential of a lossless subwavelength high-index-contrast metastructure as a broadband active coherent polarization control element. A parametric optimization of the metastructure is performed to determine its robust working parameter space. Using rigorous coupled wave analysis, we show that there exist large sets of suitable designs in the geometric parameter space capable of supporting wide-band dynamic polarization control functionalities, including reconfigurable polarizing beam splitting and arbitrary linear polarization rotation, over the entire S, C, and L communication bands. To understand the uniaxial anisotropic behavior of the subwavelength grating metastructure, we further perform a mode analysis to interpret its effective anisotropic performance. Our work provides guidance and insight for designing such subwavelength metastructures for a wide range of applications of active polarization control. [ABSTRACT FROM AUTHOR] |
