Recently, the research group of Prof. Jun He and Associate Prof. Yingwei Wang from the School of Physics, Central South University observed the polaronic state assisted sub-bandgap saturable ...

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 ...

Organic Non-Linear Optical (NLO) Materials have emerged as a promising field of study within the realm of chemistry. These materials possess unique optical properties that enable the manipulation and ...

In the context of the continuous development of high-speed optical communication, on-chip optical information processing is regarded as the core of ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...
