Figure | Schematic of the experimental configuration to generate and detect THz third harmonic generation. A multicycle driving field at the frequency w is transmitted through a lowpass filter. Inside ...
For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the nonlinear junction ...

Photonics breakthrough traps light on-chip for millions of cycles
A photon enters a tiny disk of layered crystal no wider than a human hair. It circles the rim, bouncing along atomically smooth walls, and keeps going. One lap. A thousand. A hundred thousand. By the ...
Nonlinear optical processes in the technologically important terahertz (THz) spectral range have gained increasing attention for their potential to revolutionize fields such as wireless communication ...
