All-dielectric metasurface lenses for focal plane arrays operating in mid-wave infrared spectrum
Focal plane arrays (FPAs) as a two-dimensional detector pixel matrix positioned in the focal plane of an optical system have been developed continuously for obtaining higher resolution. On the other hand, for developing ...
Analysis of the focusing crosstalk effects of broadband all-dielectric planar metasurface microlens arrays for ultra-compact optical device applications
(Optical Soc Amer, 2018-10-15)
Microlens arrays have been widely used for different optoelectronic applications. The demand for compact optical devices necessitates the deployment of even smaller microlens arrays; however, as the spacing between individual ...
Polarization independent high transmission large numerical aperture laser beam focusing and deflection by dielectric Huygens' metasurfaces
(Elsevier Science Bv, 2017-10-15)
In this letter, we propose all-dielectric Huygens' metasurface structures to construct high numerical aperture flat lenses and beam deflecting devices. The designed metasurface consists of two-dimensional array of all ...
