New device for symmetry-breaking-induced optical nonlinearity

Second-order nonlinear optical processes play a pivotal role in both classical and quantum applications, ranging from extension of the accessible frequencies to generation of quantum entangled photon pairs and squeezed states. ...

Lowering the cost for surface patterning plastics

Researchers at the Department of Micro- and Nanosystems at KTH have developed a new way to simultaneously shape and surface treat plastic components. The new method can reduce the manufacturing cost of medical devices, such ...

New printing process makes three-dimensional objects glow

Conventional electroluminescent (EL) foils can be bent up to a certain degree only and can be applied easily onto flat surfaces. The new process developed by Karlsruhe Institute of Technology (KIT) in cooperation with the ...

Stronger, longer-lasting fuel cell technology
