Nonlinear optics is the branch of photonics that studies material responses wherein the induced polarisation is not directly proportional to the applied electromagnetic field. In these media, intense ...
Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...
"Our nonlinear system transmits quantum information with 94% fidelity, compared to the theoretical limit of 33% on systems using linear optical components," said Kejie Fang, an Illinois professor of ...
