Traps for Quantum Sensing: Atomic Clocks & Precision Spectroscopy

Quantum sensing is driving a new era of ultra-precise measurement systems. From optical atomic clocks to precision spectroscopy, these technologies demand extreme mechanical stability, optical alignment accuracy, and long-term vacuum compatibility.

At FEMTOPRINT, we fabricate custom 3D glass microstructures with micrometric tolerances, ideal for high-performance quantum sensing platforms. Our proprietary femtosecond laser microfabrication enables fully monolithic integration of optical and mechanical features—reducing drift, minimizing assembly errors, and enhancing performance in UHV environments.

Technical Highlights

  • Geometrical precision: ±1 µm XY / ±2 µm Z
  • Surface roughness on machined surfaces 100-300 nm, < 10 nm if postprocessing is applied
  • Aspect ratio: ≥ 1:500 for stable optical cavities
  • Deposition of metallic coatings with sputtering or evaporation techniques
  • Vacuum-compatible dielectric coatings available on request
  • Material: Fused silica (SiO₂), ULE®, and custom optical glasses
  • Integration: Optical waveguides, fiducials, and micro-optical cavities

 

Applications in Quantum Sensing

  • Optical lattice clocks with accuracy beyond 10⁻¹⁸ fractional frequency instability
  • Precision molecular spectroscopy for quantum reference standards
  • Compact interferometric sensors for acceleration, gravity, and field detection
  • Ion and neutral atom traps for portable timekeeping systems

 

Why FEMTOPRINT technology for Quantum Sensing

  • No bonding or assembly: Monolithic structures to reduce alignment error and instability
  • Multi-layer structures bonded through laser welding
  • Wafer-scale fabrication enables scalability and repeatability
  • UHV and cryo-compatible designs for long-duration quantum experiments
  • Trusted by quantum labs, OEMs, and academic researchers across Europe and the U.S.
