Jury343_KJuly 13, 2018: The KIT project team DELPHI (3D Laser Lithography for Photonic Integration), headed by Prof. Dr. Christian Koos together with Vanguard Photonics GmbH won Second Prize of the Berthold Leibinger Innovationspreis 2018.

Prof. Dr. Christian Koos (1,2),  Alois Hauk (2),  Philipp-Immanuel Dietrich (1,2),  Dr. Nicole Lindenmann (1),  Andreas Hofmann (3),  Tobias Hoose (1),  Muhammad Rodlin Billah (1,2),  Matthias Blaicher (1)

DELPHI is dedicated to industrial adoption of femtosecond laser lithography as a tool for 3D additive nanofabrication in integrated photonics. The concept of multi-photon polymerization is exploited to fabricate single-mode photonic waveguides and free-form micro-optical elements for efficient coupling of optical chips.

The Berthold Leibinger Innovationspreis has been called for internationally since 2000. It was complemented in 2006 with the Berthold Leibinger Zukunftspreis for research. Both prizes are presented every two years at the award ceremony, an established event and meeting place of the large laser community of researchers and users with representatives of industry, politics, and society. The invention of the laser in the middle of the twentieth century was a quantum leap: light could now be tailored to specific needs, working very precisely and without physical contact. The advancement and acknowledgement of outstanding development and scientific work on the application or generation of laser light is one of the objectives of the Berthold Leibinger Stiftung.
