About Qlibri

Our mission is to harness the power of microcavities to spark innovation, enable breakthroughs, and advance human knowledge, while fostering empathy, sustainability, and responsibility in a diverse global society.


During our work in the group of Nobel prize laureate Theodor W. Hänsch at LMU Munich and the Max-Planck-Insitute of Quantum Optics, where fiber-based microresonators were pioneered, we discovered the tremendous potential of this technology across a wide range of fields. Our goal is to reduce the complexity and time required to build and operate an optical Fabry-Perot microcavity, enabling scientists and developers to accelerate their research and boost innovation.


To achieve this, we provide highly reflective mirrors, ultra-stable mechanics, low-noise electronics, adaptive software, and expert consulting—delivering high-performance microcavity solutions to our customers as efficiently as possible.


Qlibri wants to enable people and ideas to thrive, inspire innovation, and support breakthroughs while fostering a happy, inclusive, and diverse work environment. We aim to be a role model for how businesses can operate ethically, sustainably, and empathetically, prioritizing collaboration over competition.


Founders: Dr. Thomas Hümmer, Dr. Jonathan Noé, Dr. Manuel Nutz, Dr. Michael Förg

We are lucky to be supported by excellent scientific advisors:

Prof. Theodor W. Hänsch (LMU, MPQ), Prof. David Hunger (KIT), Prof. Alexander Högele (LMU)
