“…Optical frequency references based on Doppler-free spectroscopy of molecular iodine near 532nm are a well-proven technology developed in several laboratories for many years, also in compact setups [5,6,7,8,9]. Development for applications in space is ongoing, resulting in compact and ruggedized setups [1,2,3,10,11]. In a collaboration of the German Aerospace Center (DLR Institute of Space Systems, Bremen), the University Bremen (Center of Applied Space Technology and Microgravity, ZARM), the Humboldt-University Berlin and the space company Airbus Defence & Space (Friedrichshafen), several setups for space applications have been developed in the last years, including a setup on Elegant Breadboard (EBB) and Engineering Model (EM) level.…”

“…While EBB and EM setups use AOMs for phase modulation, an EOM is used here because the corresponding driver electronics has lower power consumption and is less complex and easier to implement. An ARM based embedded system for autonomous control of the experiment is used (provided by Menlo Systems GmbH) and an automatic frequency locking and relocking is implemented (developed at the Humboldt-University Berlin) [3].…”

“…The frequency stability was measured before and after the tests where no degradation was observed [2]. A very compact spectroscopy setup for use on a sounding rocket mission, successfully launched in May 2018, was implemented using micro-integrated external cavity diode lasers (ECDLs) as light source [3]. An iodine-based reference was compared to a microwave reference via an optical frequency comb, resulting in a test of local position invariance (LPI).…”

A variety of future space missions rely on the availability of high-performance optical frequency references with applications in fundamental physics, geoscience, Earth observation and global satellite navigation systems (GNSS). Examples are the gravitational wave detector LISA (Laser Interferometer Space Antenna), the Earth gravity mission NGGM (Next Generation Gravity Mission) and missions, dedicated to tests of Special Relativity, e.g. by performing a Kennedy-Thorndike experiment testing the boost dependence of the speed of light. In this context, we developed optical frequency references based on Doppler-free spectroscopy of molecular iodine where compactness and mechanical and thermal stability are main design criteria. We demonstrated a frequency instability of 610 -15 at 1 s integration time and 310 -15 for integration times between 100 s and 1.000 s. Furthermore, a very compact spectroscopy setup was realized for the sounding rocket mission JOKARUS which was successfully flown in May 2018. In a current activity, an integrated high-performance iodine-based frequency reference is developed which serves as a demonstrator for future GNSS using optical technologies.

Lasers precisely stabilized to known transitions between energy levels in simple, well‐isolated quantum systems such as atoms and molecules are essential for a plethora of applications in metrology and optical communications. The implementation of such spectroscopic systems in a chip‐scale format would allow to reduce cost dramatically and would open up new opportunities in both photonically integrated platforms and free‐space applications such as lidar. Here the design, fabrication, and experimental characterization of a molecular cladded waveguide platform based on the integration of serpentine nanoscale photonic waveguides with a miniaturized acetylene chamber is presented. The goal of this platform is to enable cost‐effective, miniaturized, and low power optical frequency references in the telecommunications C band. Finally, this platform is used to stabilize a 1.5 µm laser with a precision better than 400 kHz at 34 s. The molecular cladded waveguide platform introduced here could be integrated with components such as on‐chip modulators, detectors, and other devices to form a complete on‐chip laser stabilization system.

Modern quantum technologies have matured such that they can now be used in space applications, e.g., long‐distance quantum communication. Here, the design of a compact true single photon source is presented that can enhance the secure data rates in satellite‐based quantum key distribution scenarios compared to conventional laser‐based light sources. The quantum light source is a fluorescent color center in hexagonal boron nitride. The emitter is off‐resonantly excited by a diode laser and directly coupled to an integrated photonic processor that routes the photons to different experiments performed directly on‐chip: i) the characterization of the single photon source and ii) testing a fundamental postulate of quantum mechanics, namely the relation of the probability density and the wave function (known as Born's rule). The described payload is currently being integrated into a 3U CubeSat and scheduled to launch in 2024 into low Earth orbit. Therefore the feasibility of true single photon sources and reconfigurable photonic circuits in space can be evaluated. This provides a promising route toward a high‐speed quantum network.
