Work by an internationally renowned University of Rochester professor may offer an alternative to the way in which researchers have approached some photonics applications. Photonics applications rely ...

Nonlinear optics, a study of how light interacts with matter, is critical to many photonic applications, from the green laser pointers we're all familiar with to intense broadband (white) light ...

Researchers have recently reported on the direct observation of a nonlinear-optical effect, occurring in the regime of single-cycle pulse of light at terahertz (THz) frequencies. They used a doped ...

Nonlinear optical materials such as silicon can be used to make on-chip devices that break dynamic reciprocity. (Courtesy: K Xia) A new method for making devices that act like a “one-way street” for ...

Neural networks are one typical structure on which artificial intelligence can be based. The term ›neural‹ describes their learning ability, which to some extent mimics the functioning of neurons in ...

In the 1960s, physicists showed how light could interact with itself in intriguing ways thanks to a process known as second-harmonic generation. In the right kind of material, two photons of a certain ...

Engineering researchers report that they developed a new, efficient way to modulate and enhance an important type of nonlinear optical process: optical second harmonic generation -- where two input ...
