TRIM: Simultaneous Thermometry, Ranging, and Imaging via a Monolithic Metalens

Advanced Science, EarlyView.
ABSTRACT While metasurfaces offer a pathway beyond the discrete architectures of conventional LWIR systems, physically fusing high‐precision thermometry and passive ranging onto a single metalens remains a formidable challenge. Here, we demonstrate a monolithic, dual‐focus metalens capable of simultaneous multidimensional sensing.

Exploring Strategies to Contact 3D Nano-Pillars

Nanomaterials, 2020
This contribution explores different strategies to electrically contact vertical pillars with diameters less than 100 nm. Two process strategies have been defined, the first based on Atomic Force Microscope (AFM) indentation and the second based on ...

Observation of waveguide Fabry-Perot lasing in highly efficient Si nanocrystals

Results in Physics, 2022
A luminescent Si nanocrystal (SiNC) thin film with photoluminescence quantum yield (PLQY) > 70% was made by using hydrogen silsesquioxane (HSQ), followed by long-time high-pressure hydrogenation.

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

Ridge waveguide using highly oriented BaTiO3 thin films for electro-optic application

Journal of Asian Ceramic Societies, 2014
In this work, 750 nm-thick BaTiO3 thin films with highly (0 0 1) preferred orientation were grown on single crystal MgO substrates by RF-sputtering. Hydrogen silsesquioxane (HSQ) resist material based ridge waveguides, which were fabricated on BaTiO3 ...

Rethinking Interpersonal Humour in Organizations: Clarifying Constructs and Charting A Path Forward

Journal of Management Studies, Volume 63, Issue 6, Page 2965-3002, September 2026.
Abstract Organizational humour research is accelerating; however, scholars seem to disagree on how to conceptualize and operationalize interpersonal humour. A widely used approach draws from personality psychology and conceptualizes humour as a typology of four styles.

From Doping to Polarity Control: Transport Switching in Silicon Nanowire Field‐Effect Transistors

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
Junctionless nanowire transistors (JNTs) based on phosphorus‐doped silicon demonstrate electrostatic polarity control, ambipolar and unipolar modes, and scalable short‐channel performance. Tunable gate configurations and doping levels enable high on/off ratios and CMOS compatibility, highlighting JNTs as promising candidates for reconfigurable, next ...

Interplay Between Bound State in the Continuum and the Generalized Kerker Effect in Plasmonic Metasurfaces

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
A plasmonic metasurface comprising gold cylinders of tailored dimensions exhibits simultaneously the generalized Kerker effect and a bound state in the continuum, allowing for a detailed study of the subtle interplay between these phenomena. The numerical simulation results are in good agreement with experimental measurements, and the underlying ...
