Top Female Scientists for 2023
Ursula Keller is ranked 4 in Switzerland among Top Female Scientists for 2023
Toxic workplaces drive women away from STEM fields
Prof. Keller is increasingly concerned about “hostility” towards excellent women in leadership positions in STEMM (i.e. science, technology, engineering, mathematics and medicine) fields, which she sees as a key challenge for further progress in gender diversity. In this news item Prof. Keller summarizes her talk given first at CLEO USA 2023 as a plenary talk and more recently at an IEEE meeting in Italy.

Electrons: collective or independent – that sometimes lies in the eye of the beholder
Absorption of light adds energy to a material. The electrons inside the material can react collectively or independently to that energy. Here, the dominant reaction pattern should not depend on perspective. However, in compound semiconductors, surprisingly, divergent responses are obtained depending on which atomic constituent is consulted. Knowledge of both perspectives is necessary to optimize new materials for applications in electronics and optoelectronics.

Two new methods for multiplexing a single laser cavity to support a pair of low noise optical frequency combs
We have invented two new methods for multiplexing a single laser cavity to support a pair of noise-correlated, yet cavity length independent optical frequency combs.
