High-Beam-Quality Meta-Grating Couplers for Large Collimated Free-Space Beams on Silicon-on-Insulator
Max Schittenhelm, Sebastian Häfner, Steffen Sauer +1
Photonic integrated circuits on the silicon-on-insulator (SOI) platform typically interface with free space via grating couplers, but scaling these to collimated beams with diamete…
Laser stabilized to a room temperature cavity with AlGaAs coatings reaching fractional frequency instability
Chun Yu Ma, Jialiang Yu, Steffen Sauer +6
We present a laser system referenced to a room-temperature ultrastable cavity employing crystalline AlGaAs coatings. We demonstrate a fractional frequency instability of $4.2 \time…
Benchmarking Dual-Polarization Silicon Nitride Photonic Integrated Circuits for Trapped-Ion Quantum Technologies
Carl-Frederik Grimpe, Anastasiia Lüßmann-Sorokina, Guochun Du +10
Trapped ions are one of the most advanced platforms for quantum technologies, with applications ranging from quantum computing to precision timekeeping. A crucial step towards more…
Guidelines for designs for ultrastable laser with fractional frequency instability
Joannès Barbarat, Erik Benkler, Marcin Bober +46
Lasers with long coherence time and narrow linewidth are an essential tool for quantum sensors and clocks. Ultrastable cavities and laser systems are now commercially available wit…
Mechanical loss and stability analysis of NEXCERA in ultra-stable optical cavities
Nico Wagner, Mateusz Narożnik, Marcin Bober +3
NEXCERA has emerged as a ceramic-based material for spacers in ultra-stable optical cavities, with a coefficient of thermal expansion that crosses zero near room temperature. In su…
