Abstract
The emergence of metasurface technology and its accompanying design principles are enabling the development of optical components with multiple functionalities, e.g., polarization discrimination and focusing. In this report, we highlight our experimental results associated with the characterization of a reflective mid-wave infrared (mid-IR) metasurface designed for both imaging and polarization-specific beam splitting in the 4.2 through 4.8 m region of the electromagnetic (EM) spectrum. A large area metasurface (1 cm diameter), fabricated using nano-lithography, was observed to exhibit a high degree of discrimination between transverse electric (TE) and magnetic (TM) polarized light with near diffraction limited focusing.
