The Center for Coherence and Quantum Optics (CCQO) is a collaboration of researchers from a range of disciplines across the University of Rochester. By pooling our skills and resources, we push the frontiers of the field of quantum and classical coherence to new areas. We also enable practical applications within the areas of optical science and optical engineering.
Two University of Rochester scientists have found a way of using powerful laser beams to make metal surfaces last longer and be more suitable for a wide range of practical purposes. "We change the nature of the metal surface so that they can repel water," said Chunlei Guo, who is a professor of optics and physics at UR.
In a paper featured on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a recently developed theory for predicting the most likely path a system will take between two states.
Physicists at the University of Rochester have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics evolutionary biology, allowed them to achieve a 10-fold improvement on the performance of previous nanocavities.
