InSynQ: Integrated Synchronizable Laser Source for Quantum Sensing

With quantum technologies, such as quantum computers and clocks, maturing from academic proof-of-principle achievements towards commercialization, there is a growing demand for key-enabling technologies and critical components to secure the underlying supply chain and enable straightforward manufacturing by and procurement from European sources. This particularly includes scalable light sources and detectors, with passive and active components based on photonic integrated circuits serving as an ideal solution to fulfill this demand.

In the Dutch-German research project “InSynQ”, the consortium will make a significant step to closing this technology gap by developing narrowband lasers and (balanced) photodetectors based on the indium phosphide platform, taking into account a fully European supply chain that includes chip design and fabrication, testing, and packaging, so the resulting circuits can be directly applied by end-users in quantum technologies.

In particular, Menlo Systems will take care of testing, packaging and applying the cutting-edge chips developed by project partner TU Eindhoven, a global leader in the field of active photonic components. The applicability of the components will then be demonstrated by integrating them into a synchronizable laser source that enables direct linking towards an optical frequency comb, an ultrastable optical reference system, or integration into a quantum clock .
