Welcome to the website of Prof. Dr. Martin Wegener's research unit "Nanophotonics" at the Institute of Nanotechnology.

Our research focuses on the fabrication and characterization of functional photonic materials and microscopic optomechanical circuits. We also develop advanced lithography and replication approaches to fabricate these materials and devices.

An elasto-mechanical unfeelability cloak made of pentamode metamaterials

KIT researchers have created the first mechanical invisibility cloak. When placed over an object, the object cannot be felt at all — either by a finger, or a more sensitive measuring device.

KIT Forscher bauen optische Tarnkappe für Nebel
Invisibility cloaking in a diffusive light scattering medium Researchers at the KIT have developed a cloak that is broadband, omnidirectional, and big enough to hide a macroscopic object. The new cloak works  in foggy or "diffusive" conditions.
