POLARIZATION-SELECTIVE ELEMENTS WITH A SUBSTRATE-MODE GRATING PAIR STRUCTURE

Abstract

A novel device with a substrate-mode grating pair structure to perform the function of polarization selection is presented. Normally incident and output coupling of this compact and lightweight component provides better flexibility and easier alignment for system applications. A highly polarization-selective substrate-mode grating pair has been designed and fabricated. Polarization-selective switching experiments with this device are demonstrated.
