Origin, Strength, and Speed of the Nonlinear Optical Response of Transparent Conducting Oxides to Single‐Cycle Optical Pulses

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A quantum‐coherent density‐matrix study reveals a predominantly cumulative thermo‐optic nonlinear response in ITO under extremely short pulses, with coherent electron dynamics leaving signatures in macroscopic polarization and permittivity. Remarkably, the permittivity dynamics are accurately reproduced by a simple thermal model. We also generalize the

From sub-Terahertz to Terahertz: challenges and Design Considerations

2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2020
NR Rel-15 physical layer specifications (released on December 2018) by 3GPP targeting IMT 2020 can support deployments in frequency ranges 410 MHz - 7.125 GHz and 24.25 GHz - 52.6 GHz. The support of higher frequency bands with large chunks of contiguous spectrum was deemed essential to fulfilling IMT 2020 vision of 20 Gbps peak data- rate in realistic

A Terahertz-Transparent Electrochemical Cell for In Situ Terahertz Spectroelectrochemistry

Analytical Chemistry, 2018
Terahertz spectroscopy is broadly applicable for the study of a wide variety of materials, but spectroelectrochemistry has not been performed in the THz range because of the lack of a THz-transparent electrochemical cell. While THz-transparent electrodes do exist, they have never been utilized in a complete three-electrode cell, which is the ...
