For the first time ever, physicists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in proving that an optical system can be ‘invisible' from one side and act like a mirror from the other side. The study has been published in Nature.

Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers and solar cells.

Conventional imaging devices are limited in their resolution and, hence, restrict the insights into structures smaller than the wavelength. Near-field microscopy overcomes this limitation by probing evanescent fields resulting in a wavelength-independent resolution. A superlens is a planar device, which transforms these fields to an image plane. We study such lenses for the infrared based on perovskite oxides, which might be applicable to imaging of highly-damped samples e.g. in liquids.

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones.
