Core offering

Qlibri designs, manufactures, and sells high-precision photonic instrumentation based on fiber-based Fabry-Perot microcavities. Its offerings span complete turnkey scanning microcavity platforms (CP-Pro, CP-Compact) for cryogenic quantum-optics experiments, ultra-sensitive absorption microscopes (Qlibri Nano) and an optical coating analyzer for nanoscale defect detection, and individual high-reflectivity fiber microcavity mirrors. Products target researchers, developers, and engineers in academia and industry working on quantum optics, nanophotonics, cavity QED, and cavity-enhanced spectroscopy.

Product overview

Qlibri offers a portfolio of optical microcavity technology products ranging from individual components to complete turnkey platforms. The core products include CP-Pro and CP-Compact microcavity platforms (turnkey scanning cavity systems for cryostats), Qlibri Nano absorption microscope and Optical Coating Analyzer (ultra-sensitive resonator-enhanced imaging systems), and Fiber Cavity Mirrors (high-reflectivity micromirrors for cavity-based experiments). Optional add-on modules include Magnetic Field Upgrade and Active Stabilization Module for the microcavity platforms, and High-Resolution Spectroscopy Module for the absorption microscope. All products are designed for researchers, developers and engineers in academia and industry working with light-matter interaction, quantum optics, and nanophotonics.

Broad incumbents

• Toptica Photonics: Toptica manufactures diode and ultrafast lasers, frequency combs, and spectroscopy systems for quantum optics, cold atom, and metrology applications. Comparable to Qlibri as a Munich-based photonics supplier serving the same academic quantum research customer base, but with a broader product portfolio spanning lasers rather than microcavities.
• Thorlabs: Thorlabs is a large catalog supplier of photonics components including optical fibers, mirrors, mounts, and integrated optomechanical systems. Comparable to Qlibri's Fiber Cavity Mirrors product in offering optical components for cavity experiments, but as a broad incumbent with much wider catalog coverage across optics and photonics.
• Zurich Instruments: Zurich Instruments makes lock-in amplifiers, quantum analyzer controllers, and arbitrary waveform generators used in quantum optics and qubit readout. Comparable as a supplier of measurement and control instrumentation to the same quantum optics customer base that Qlibri serves with its microcavity platforms.

Direct peers

• Stable Laser Systems: Stable Laser Systems builds ultra-high-finesse optical cavities and frequency references for precision laser stabilization, atomic clocks, and quantum sensing. Comparable to Qlibri in providing high-finesse Fabry-Perot cavity technology and stability solutions, though focused on larger-scale reference cavities rather than fiber-based microcavities.
• Qnami: Qnami produces quantum sensing and imaging instruments using NV-diamond technology for nanoscale magnetic field imaging. Comparable to Qlibri Nano in delivering ultra-sensitive, scanning-probe-style detection of nanoscale features, with similar application overlap in materials science and quantum device characterization.
• attocube systems: attocube manufactures cryogenic nanopositioning and scanning probe microscopy systems used in quantum optics and condensed matter research. Overlap with Qlibri's CP-Pro/Compact microcavity platforms in serving cryogenic cavity QED and low-temperature light-matter coupling experiments, with both companies addressing the same low-temperature quantum optics lab market.

Emerging players

• Menlo Systems: Menlo Systems develops optical frequency combs, ultrastable lasers, and femtosecond lasers for precision metrology and quantum applications. Comparable to Qlibri in serving high-precision laser and quantum optics labs with technology that complements Qlibri's microcavity stabilization offerings.
• AOSense: AOSense builds atom-based quantum sensors including gravimeters, accelerometers, and magnetometers, and supplies frequency-stabilized laser systems. Comparable to Qlibri in addressing the quantum sensing and precision measurement customer segment with adjacent enabling components.
• ID Quantique: ID Quantique provides quantum sensing instruments and quantum key distribution systems, with cavity-enhanced components in its product line. Comparable as a European quantum technology vendor serving R&D customers with overlapping presence in the QR.X quantum networking and biosensing ecosystems.

Others

• Ligentec: Ligentec manufactures silicon nitride photonic integrated circuits for quantum and sensing applications. Not a direct competitor but an adjacent enabling technology provider in the European photonic-quantum ecosystem that may ultimately integrate with or compete against Qlibri's fiber-based microcavity architecture.
