Abstract

Nonperiodic molybdenum/silicon broadband multilayer polarizers are designed using numerical optimization algorithm and fabricated using direct current magnetron sputtering. The multilayer polarizers show a high s reflectivity and polarization over a broad angular range at fixed wavelength.

Abstract

Transmission characteristics were studied for hybrid structures combining defects and multiple heterostructures. The study shows that the nontransmission frequency range can be substantially enlarged and the phenomenon of multiple-channeled filtering can be realized by adjusting the number, position, and size of the defects.
