Reconfigurable Imaging Systems Using Elliptical Nanowires
Nanoletters – Materials that have subwavelength structure can add degrees of freedom to optical system design that are not possible with bulk materials. Researchers demonstrate two lenses that are composed out of lithographically patterned arrays of elliptical cross-section silicon nanowires, which can dynamically reconfigure their imaging properties in response to the polarization of the illumination. …
