Continued development in the areas of communication, security, medicine, and safety is
calling for terahertz‐wave technologies to evolve beyond laboratory research and into the …

A GaSe crystal cut along the (001) crystallographic plane is investigated for the emission
and detection of high-frequency (ie up to∼ 20 THz) electric fields. To date, a comprehensive …

Surface modification of nonlinear optical materials (NOMs) is widely applied to fabricate
diverse photonic devices, such as frequency combs, modulators, and all‐optical switches. In …

Miller's rule is an empirical relation between the nonlinear and linear optical coefficients that
applies to a large class of materials but has only been rigorously derived for the classical …

We report on narrowband terahertz (THz) radiation generation via optical rectification from a
BaGa_4Se_7 crystal. The dense phonon mode distribution of the BaGa_4Se_7 crystal …

An emerging crystal, CdSiP2, is shown to exhibit a higher nonlinearity than other key electro-
optic sampling crystals, while also satisfying the electro-optic sampling phase-matching …

A nonlinear finite-difference time-domain (FDTD) formalism is developed to model
dispersive second-order nonlinear effects in photonic arrangements and optical devices …

In this study, we proposed a hologram calculation method for light-in-flight recording by
holography (LIF holography). First, we simulated the behavior of ultrashort pulsed light on …

A comprehensive modeling approach for elucidating the intricacies of electro‐optic (EO)
sampling is presented, which fully encapsulates the EO sampling process by accounting for …

The backward difference frequency generation process is used to produce narrowband
terahertz radiation via modal phase-matching in a SiO_2-LiNbO_3-air planar waveguide …
