Breitband: Provider liefern mehr Leistung – oft aber noch nicht die bezahlte
Der 9. Bericht der Bundesnetzagentur zur Breitbandmessung bringt gemischte Ergebnisse. Im Festnetz sieht es weiter teils recht düster aus, 5G kommt aber voran.

Wat een naar verhaal en slecht voor Nederland. "Als er kamerleden voor de commissie Digitale Zaken gevonden moeten worden steekt bijna niemand in Den Haag zijn of haar hand op. Want iedereen weet, het kost je je carrière als je te digitaal bent."

De Digitale Bermudadriehoek in Den Haag - Bert Hubert's writings
Als er kamerleden voor de commissie Digitale Zaken gevonden moeten worden steekt bijna niemand in Den Haag zijn of haar hand op. Want iedereen weet, het kost je je carrière als je te digitaal bent. Je partij straft je af met een lullig positie op de lijst voor de volgende verkiezingen. Dit gebeurde harde werkers Hind Dekker en Lisa van Ginneken al eerder. En zo blijkt het ook dit jaar alweer te gaan.

Beyond the Black Box: Integrating Lexical and Semantic Methods in Quantitative Discourse Analysis with BERTopic
Quantitative Discourse Analysis has seen growing adoption with the rise of Large Language Models and computational tools. However, reliance on black box software such as MAXQDA and NVivo risks undermining methodological transparency and alignment with research goals. This paper presents a hybrid, transparent framework for QDA that combines lexical and semantic methods to enable triangulation, reproducibility, and interpretability. Drawing from a case study in historical political discourse, we …

Design of broadband optical gain in GaSb-based waveguide amplifiers with asymmetric quantum wells
A design strategy for achieving broadband optical gain in GaSb-based semiconductor amplifiers operating beyond 2 μm is presented. By employing asymmetric GaInSb/AlGaAsSb quantum wells (QWs) of varying thicknesses, a flat and wide gain spectrum is demonstrated. The approach leverages carrier density and transition energy tuning across QWs to access various energy levels at specific current densities. Simulations using "Harold" self-consistent environment predict a full-width at half-maximum (FW…

Compact broadband thermal absorbers based on plasmonic fractal metasurfaces
The ability to efficiently absorb thermal radiation within a small material volume is crucial for the realization of compact and high spatial resolution thermal imagers. Here we propose and experimentally demonstrate a compact plasmonic metasurface for broadband absorption in the 6 to 14 microns wavelength range. As opposed to previous works, our metasurface leverages strongly localized electromagnetic modes to achieve high absorption within a compact form factor. We numerically investigate the…

Broadband nonlinear optical microresonator array for topological second harmonic generation
Topological photonics enables robust light manipulation with third-order optical nonlinearity, yet integrating second-order optical nonlinearity into a topological system faces fundamental challenges: frequency-dependent topological bandgaps impede simultaneous edge states for pump and second harmonic photons at an octave. Here we present a broadband topological nonlinear photonic system via dual frequency topological bandgap engineering in a 2D nonlinear microresonator array. By designing a sq…

Broadband amplification of light through adiabatic spatiotemporal modulation
Four-dimensional optics leverages the simultaneous control of materials in space and time to manipulate light. A key challenge in experimentally realizing many intriguing phenomena is the need for rapid modulation, which is hindered by the inherently adiabatic relaxation of optical materials. Here, we theoretically demonstrate that broadband amplification can be achieved without the need for sub-cycle temporal responses, instead leveraging adiabatic spatiotemporal modulation patterns. The propo…
