Extremely cold and highly efficient: Scientists present new light fiber
Researchers have developed a new type of optical fiber by freezing a glass capillary filled with liquid. It guides light and sound waves simultaneously and enables highly efficient coupling between them. The high coupling strength lowers the energy consumption of photonic neuromorphic computing…
Inaugural Lecture of Prof. Dr. Birgit Stiller at Leibniz University Hannover
The Stiller RG group packed their suitcases this week and travelled to Hannover for the inauguration of Birgit Stiller. The lecture gave a fantastic overview over the groups work and we celebrated with our new “1. FG Stiller” scarfs and a big buffet. Additionally, we got a tour through the…
New paper on the arxiv: higher-order exceptional points induced by Brillouin optoacoustics
We report the first experimental implementation of a third-order exceptional point (EP3) in a fabrication-free photonic system, leveraging multi-frequency stimulated Brillouin scattering in a single-mode optical fiber. By performing a multi-dimensional parameter scan, we successfully mapped not only…
New paper on the arxiv: Quantum memory in a continuous optoacoustic system
In this paper, we propose a quantum memory protocol based on Brillouin scattering in an optical waveguide. We show how this concept enables broadband quantum state storage without relying on discrete cavity modes and identify continuum Brillouin optomechanical systems as a scalable platform for…
Congratulations to Charlotte Finger on being an Optica Women Scholar 2026!
With the Optica Women Scholars program, the Optica Foundation recognizes 20 outstanding early-career women researchers world-wide in optics and photonics each year. In addition to financial support, the awardees receive access to mentoring, an international community, and a one-year Optica Student…
New paper on the arxiv: Giant Brillouin gain in frozen CS2 capillaries
In this preprint we experimentally demonstrate the freezing of CS2-filled and fully sealed liquid core optical fibers to achieve a giant Brillouin gain. We utilize this high gain to create an optoacoustic memory with very low power usage and illustrate how this new platform can help boost the…
