Disentangling spin polarization from driven circular ionic motion in EuTiO
Clifford J. Allington, Matthew J. Lutz, Enoch +31
Coherently driven circular ionic motion has been reported to produce large helicity-dependent optical responses attributed to transient magnetization. However, the microscopic natu…
Predicting THz Generation Capability of Organic Crystals through Data Mining and Crystal Nonlinearity Models
Sin Hang Ho, Ashton Roma, Connor Barlow +5
We report the use of DFT computation and mathematical models to predict the nonlinear dielectric polarization (P^{NL}) and nonlinear susceptibility coefficients (χ^{(2)}_{IJK}) of…
ZPAN: An Organic Nonlinear Optical Crystal for High Intensity THz Generation
Matthew J. Lutz, Sin-Hang Ho, Zachary B. Zaccardi +5
We report an optimized synthesis and crystal growth protocol as well as structural, optical, and terahertz (THz) generation characteristics of the organic nonlinear optical crystal…
Ultrafast Faraday Rotation Probe of Chiral Phonon-Polaritons in LiNbO3
Megan F. Biggs, Sin-hang, Ho +4
Time reversal symmetry breaking motion of chiral phonon-polaritons in LiNbO3 is probed via the ultrafast Faraday effect. By combining a pair of perpendicularly polarized THz pulses…
A new standard in high-field terahertz generation: the organic nonlinear optical crystal PNPA
Claire Rader, Zachary B. Zaccardi, Sin Hang +6
We report the full characterization of a new organic nonlinear optical (NLO) crystal for intense THz generation: PNPA ((E)-4-((4-nitrobenzylidene)amino)-N-phenylaniline). We discus…
Data Mining for Terahertz Generation Crystals
Gabriel A. Valdivia-Berroeta, Zachary B. Zaccardi, Sydney K. F. Pettit +13
We demonstrate a data mining approach to discover and develop new organic nonlinear optical crystals that produce intense pulses of terahertz radiation. We mine the Cambridge Struc…
Enabling High-Power, Broadband THz Generation with 800-nm Pump Wavelength
Zachary B. Zaccardi, Isaac C. Tangen, Gabriel A. Valdivia-Berroeta +7
The organic terahertz (THz) generation crystal BNA has recently gained traction as a valuable source to produce broadband THz pulses. Even when pumped with 800-nm light, thin BNA c…
