Anisotropy of Second‐Harmonic Generation in SnSe Flakes with Ferroelectric Stacking

open access: yesAdvanced Photonics Research, Volume 6, Issue 10, October 2025.
Giant second‐harmonic generation (SHG) susceptibility, on the order of 1000 pm V−1, in SnSe with ferroelectric stacking is demonstrated by theoretical and experimental methods. SHG microscopy is utilized to study few‐layer ferroelectric SnSe flakes on mica substrates. Stripe‐like features in SHG mapping indicate ferroelectric domains. Strong wavelength‐

Serrodyne‐Enabled Dual Electro‐Optic Comb Interferometry for High‐Precision Absolute Ranging and Integration‐Ready Metrology

open access: yesAdvanced Science, Volume 12, Issue 37, October 6, 2025.
A serrodyne‐modulated dual electro‐optic comb interferometer is presented that achieves sub‐nanometer precision in absolute distance measurements. The system also supports diverse applications such as depth imaging and vibration sensing. With features of low RF power, wide frequency‐shifting range, and full integration potential, the system offers a ...

Direct Observation of Suppressed Optical–Acoustic Phonon Energy Coupling in Supported SWCNT at Cryogenic Temperatures

open access: yesAdvanced Science, Volume 12, Issue 37, October 6, 2025.
This study quantifies the temperature‐dependent optical–acoustic phonon coupling factor (GOA) in supported single‐walled carbon nanotubes, revealing significant suppression at low temperatures. At high temperatures, GOA increases monotonically and is attributed to intensified anharmonic phonon interactions. This research offers key insights into phonon

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model

open access: yesAnnalen der Physik, Volume 537, Issue 10, October 2025.
Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Oscillator Chain: A Simple Model for Universal Description of Excitation of Waveguiding Modes in Thin Films

open access: yesAnnalen der Physik, Volume 537, Issue 10, October 2025.
Modulated thin films, when coupled to external fields, show Fano resonances. There is no simple analytical description of such micro‐optic schemes, therefore they are usually simulated numerically. We fill this gap of the lack of universal analytical description by introducing and exploring a simple mechanical equivalent, the oscillator chain, which ...
