#Research Group Birgit Stiller “#Quantum Optoacoustics”

Light and sound can interact in optical fibers, enabling applications ranging from photonic machine learning to #QuantumTechnologies.
A prerequisite for interactions in the quantum regime is the so-called strong coupling regime. MPL scientists have predicted and measured it in an optical fiber. This paves the way for in-line quantum signal processing.

Meet Dr. Michael Frosz & Susanne Viezens – making #science visible and advancing it

Michael heads the TDSU “Fibre Fabrication & Glass Studio” and aims to better understand the “mystery of light”.

Susanne is a graphic designer. Apart from #design, she photographs researchers at work and translates complex content into visual language.

They are connected by the joy of understanding things and creating something new together with others.

" #Microlaser detects individual molecule...." Everyone in #photonics is probably doing this now but it seems such a simple yet clever idea. #RabbitHole of the afternoon - and well enough explained for a non-specialist to follow.

"The resonators we used in this study were microspheres with diameters ranging from 70 to 110 μm, ⭐fabricated by⭐melting ⭐the tips of⭐optical⭐fibres⭐ ... dip coated with two thin layers of Yb3+-doped sol .... The resonators exhibited Q factors of 105−106 at the excitation wavelength band.

A 972-nm laser used to excite the gain medium via a tapered fibre (TF) coupled to the microlaser (Fig. 1)⬇️ , with emission typically observed between 1,030 nm and 1,100 nm. All the experiments were conducted in aqueous environments, and ytterbium was selected as it particularly provides high gain efficiency when the resonator is operated when immersed in water and emitting at a wavelength with excellent water transmission. Due to its high gain efficiency in water, sub-milliwatt excitation and lasing are enabled...."
