Active control of focal length and beam deflection in a metallic nanoslit array lens with multiple sources.
We propose an all-optical method to actively control the transmission of nanoslit arrays for scanning and lensing applications. We show that by utilizing two lateral control slits, the transmitted beam can be actively steered.
