Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators -- tiny vibrating strings -- ...

Nonlinear optics is a branch of optics that deals with the complex nonlinear relationships between the optical response of the medium and the incident light when it interacts with the optical medium.

Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next-generation applications, including high-speed wireless communications, ...

A new system for THz spectroscopy achieves both high spectral and spatial resolution at the same time, bypassing a long-standing tradeoff. (Nanowerk News) Terahertz (THz) radiation, which occupies the ...
