Nature Photonics: Terahertz-to-optical conversion for future THz communication systems
July 2019: Researchers of IPQ, IMT, and IHE in collaboration with scientists from the Fraunhofer Institute for Applied Solid State Physics (IAF) in Freiburg have demonstrated direct conversion of high-speed data signals from the terahertz (THz) domain to the optical domain using an ultra-broadband modulator. The device combines a plasmonic nanostructure with a highly efficient organic electro-optic material, offers a modulation bandwidth of more than 0.3 THz, and lends itself to high-density integration together with advanced silicon photonic circuitry. The concept of direct conversion of wireless THz data signals to optical signals offers unprecedented flexibility for integration of future THz wireless links into existing fiber-optic infrastructures.

Nature Photonics: Silicon integration of terahertz systems
October, 2018: Scientists of IPQ and IMT have demonstrated ultra-fast silicon-plasmonic devices for generation and detection of terahertz signals. The devices can be integrated on the silicon photonic platform, bringing together photonics, electronics and terahertz technologies on a common substrate. The concept offers promising perspectives for a wide variety of applications, including high-speed communications, life sciences and industrial metrology. The publication appeared in the October issue of Nature Photonics.

IPQ/IMT team receives Second Prize at the competition for the Berthold-Leibinger Innovation Prize
July 2018: The IPQ/IMT project team "DELPHI - 3D Laser Lithography for Photonic Integration" will receive the Second Prize of the renowned Berthold-Leibinger Innovation Prize. The DELPHI project group, headed by Christian Koos, was dedicated to industrial adoption of femtosecond laser lithography as a tool for 3D additive nanofabrication in integrated photonics and has led to foundation of the start-up company Vanguard Photonics GmbH. The project builds upon multi-photon lithography for fabrication of single-mode photonic waveguides and free-form micro-optical elements for efficient coupling of optical microchips. The award ceremony will take place on September 21, 2018 in Ditzingen, Germany.
