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

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...

Experimental and Computational Investigations of Surface Polaritons at Metal‐Oxide‐Semiconductor Interfaces

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
STEM‐EELS and full‐wave FDTD reveal electron‐driven surface‐polariton modes at buried Au/oxide/Si interfaces with 10 nm SiO2 or Al2O3 spacers. Extinction is dominated by non‐radiative absorption, while oxide permittivity shifts the resonance and controls evanescent‐field penetration across the spacer into silicon.

Low‐Complexity Phase–Transition‐Based VO2 Transmissive Reconfigurable Intelligent Surface for Indoor Millimeter‐Wave Communications

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.
