Terahertz (THz) radiation, occupying the spectral region between microwave and infrared frequencies, is emerging as a vital tool in fields ranging from wireless communications and spectroscopy to ...

Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, ...

a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

Frequency Electronics designs precision time and frequency generation technology for satellites and secure communication, with the majority of revenue coming from U.S. government contracts. The ...
