Abstract:

Quantum optical sensors, such as atom interferometers or optical clocks, receive increasing interest for deployment in the field and even in space, enabling various applications ranging from inertial navigation and timekeeping to geodesy, magnetic and electric field sensing, and fundamental physics experiments. However, the transition towards operation of quantum sensors in out-of-the-lab environments requires a high degree of integration and robustness across all components of these systems. In this context, we develop and realize hybrid micro-integrated photonic modules designed to meet the stringent requirements for electro-optical performance, compactness, and robustness. Based on our versatile micro-integration platform developed for the realization of compact diode laser modules [1,2], we currently expand the technology towards miniaturized Light Control Units (LCUs). These modules are designed to manipulate laser light properties, such as frequency, phase, or intensity, either provided by a separate laser module or by laser diode chips directly integrated within the LCU.
