TOPTICA, ams OSRAM, Fraunhofer to Develop Quantum Light Sources

Under the umbrella of the DigiQuant project funded by the Bavarian Ministry of Economic Affairs, TOPTICA, ams OSRAM, and the Fraunhofer Institute for Integrated Circuits IIS (Fraunhofer IIS) will develop diode-based laser technology to advance the field of quantum optics. The joint project supports market introduction of quantum computers.

Within the project, the laser diodes are to be developed at ams OSRAM. The diodes are suitable for hybrid integration of photonic waveguides and digital control electronics at TOPTICA.

Fraunhofer IIS and TOPTICA will investigate the miniaturization of electronics in integrated circuits. The effort seeks to enable the digitized operation of any material class diodes from a diverse range of manufacturers. The miniaturized and digitized subsystem will be tested in two different applications, a quantum computer application and an industrial application to read out a digital code with a hand-held scanner.
