Rolled-up hyperlens goes broadband
BM11761 - W
e demonstrate that a
rolled-up hyperlens fabricated from thin self-rolling metallic and
semi-conducting layers can be used to image sub-wavelength details over a broad
frequency range in the visible. We perform transmission and reflection
measurements on rolled-up hyperlenses and characterize their optical
properties. By means of simulations we demonstrate that two dipoles with a
sub-wavelength separation placed at the inner perimeter of the rolled-up
hyperlens create a magnified image at the outer perimeter. For our devices this
hyperlensing behavior is present in a broad wavelength range in the visible and
near-infrared regime making them particularly interesting, e.g., for
sub-wavelength imaging of biological cells in a microfluidic system.
