The power of 

optical micro-cavities

We help you to use the incredible power of optical micro-cavities to enhance light-matter interaction for quantum technologies & research and new insights through ultra-sensitive absorption microscopy

Cavity quantum optics platform

Quantum optics cavity experiments with solid state materials at 4K

Our microscopic high finesse cavity enhances light-matter interactions for applications in quantum computation, single-photon sources, quantum networks and other cutting edge research.

Use our quantum optics platform to sample thousands of inhomogeneous nanosystems like quantum dots, NV-centers, or 2D-Materials in a single run with the ability to perform quantum optics experiments on every single one of them.  

Ultra-sensitive absorption microscope

Absorption spectroscopy of low-dimensional materials  

Our microscope provides spatial-, spectral-, and time-resolved absorption measurements with exceptional sensitivity.

Measure spectrally and spatially resolved absorption of nanosystems at the parts-per-billion level. Gain new insight for material research and see what nobody else saw before.

Microscopic cavity mirrors

Microscopic cavity mirrors for your experiment and application

Highly reflective, microscopic fiber-based cavity mirrors for quantum optics, single photon sources, signal enhancement, strong light-matter interaction, filters, ion traps ... 

Precision-machined mirror profiles and high reflection coated cavity mirrors from pioneers in fiber-cavity fabrication. First commercial source. 10 years of experience in manufacturing and operating high finesse fiber-based cavities. Choose between stock and custom mirrors.

Scanning cavity technology

How our scanning cavity system works:

  1. An optical fiber with a small concave mirror.
  2. A large planar mirror.
  3. Place your sample.
  4. Find suitable nanoparticle.
  5. Couple to quantum systems / do spectroscopy.
  6. Publish!
  7. Repeat
