Berlin startup's initial product line-up includes hybrid-integrated laser systems and optical frequency references.
Germany’s Ferdinand Braun Institute (FBH), which specializes in high-specification laser diodes and LEDs, has spun out a new quantum-focused company in the form of Rydberg Photonics.
Located in the Berlin-Adlershof science and technology park, the startup is offering photonic modules aimed at applications in emerging industrial applications of quantum technology.
“The initial portfolio includes hybrid-integrated laser systems and optical frequency references – essential building blocks for quantum applications from sensing to computing,” states the firm.
Ultra-stable systems
Andreas Wicht, who also heads up FBH’s Joint Lab [for] Quantum Photonic Components, is one of five listed co-founders of the company. He said in a release from the institute:
“Our mission is to accelerate market adoption of quantum technologies by providing industry-compatible, compact, scalable, and ultra-stable hybrid-integrated photonic systems.”
Günther Tränkle, who was previously FBH director, is another co-founder and now the startup’s managing director. He added: “By combining FBH’s deep technical foundations with entrepreneurial drive, we aim to become a key enabler in the rapidly evolving global quantum tech industry.”
The three other Rydberg co-founders listed on the firm’s web site include David Anderson, who is the CEO of Michigan-based Rydberg Technologies - a separate company that provides atomic vapor cells and reference devices for laser frequency stabilization.
Also involved are the Humboldt University of Berlin professor Markus Krutzik, and scientific advisor Georg Raithel, a University of Michigan professor working on laser cooling and trapping technologies, and who also co-founded Rydberg Technologies.
Plug-and-play references
FBH says that the startup’s initial focus is on narrow-linewidth, high power, and tunable hybrid-integrated laser systems, as well as plug-and-play optical frequency references - described as crucial building blocks for “real-world” quantum applications.
“The company is already engaging in collaborations with academic and industrial partners, while actively pursuing pilot projects and joint development programs,” it added.
“[Berlin-]Adlershof offers exactly the environment a deep-tech startup like ours needs to become a key driver in shaping the next generation of quantum technologies,” commented Krutzik.
The Rydberg Photonics web site indicates that the startup is currently looking to hire a physicist to carry out optics- and laser-related research for quantum sensor technology, including prototype qualification and new product development.
