A computational study reports that modeled TiO2 films reflect less and absorb more as laser intensity rises, while absorption varies by structure mainly at weak fields.

A laboratory detector paired a bulk scintillator with a silicon-nitride metalens and reported an 8.8-fold edge-resolution enhancement. Computer simulations then projected wider CT spatial bandwidth and about fivefold lower fluence for a selected 3-mm task, but the work did not directly validate a complete clinical system.

A laboratory study demonstrated two nominally identical hBN-encapsulated graphene detectors integrated on high-resistivity silicon dielectric waveguides, reporting 11.5 V/W port-referenced responsivity, a 2.46 nW/Hz1/2 noise-equivalent power and a 1.94 GHz cutoff.

A modeling study suggests that local ring and pore geometry may shape structural color more strongly than some measures of broader order, while leaving the biological network’s exact structure unresolved.

A modeling study reports that off-center shells move plasmonic hot spots toward thinner regions and give higher-order modes finite optical coupling. Adding more metal–dielectric interfaces broadens the modeled spectral response, while nonconcentric geometries increase the density of accessible resonances.

Computer models of idealized silver nanowire dimers found that shape, corner curvature and separation were associated with changes in optical resonances and near-field enhancement, with bowtie gaps showing the largest reported values.

A laboratory-made monolayer WSe2 lens reached about 9.3% nonlinear focusing efficiency, more than 150 times its linear value, while a control beam produced about 30% focal-signal modulation below 10 µJ/cm2. The work reports a sub-0.5-picosecond component and a roughly 10-picosecond component, but does not establish performance across multiple devices.

A preprint reports InGaAs quantum-dot emission shifting across growth designs and separate demonstrations of two-dot structures in individual nanowires. An InAs segment was examined for structural and compositional compatibility, not for pure InAs quantum-dot emission in the telecom band.

A single-sensor optical prototype produced stress contrast in silicone phantoms and ex vivo mouse pancreatic, breast and liver tissue, but larger clinical studies are needed to establish diagnostic sensitivity and specificity.

Computer simulations suggest a phase-only beam shaper can produce a flatter, more even far-field beam for intersatellite optical links, but the modeled match worsened at higher order and still needs fabrication and experimental testing.

A physics preprint describes an optical imaging scheme that couples an encoding parameter to a matching decoder. In its tested simulations and passive single-pixel experiment, matched decoding recovered target structure, while naive or mismatched decoding produced structured leakage; the paper does not provide a formal proof of unconditional security.

A numerical comparison supports symmetry-matched switching between two light modes while revealing a confinement-versus-leakage trade-off during routing and modeled writing errors.

An oscillator-driven femtosecond pump–probe system measured local optical dynamics in multilayer and monolayer MoS₂. The reported setup combined an estimated whole-spectrum time resolution below 100 fs with submicrometre spatial resolution and found different long-lived responses at the centre and edge of one monolayer flake.

A model-based arXiv preprint examines how structured driving fields could control the geometry and geometric phases of high-harmonic optical cat states. Its results are theoretical calculations, not an experimental demonstration.

A modeling study describes how a two-color ultrashort laser pulse with a changing focal velocity could shape terahertz radiation. The calculations produced a parabolic wavefront in one decelerating case and a conical, ring-shaped pattern for a constant-velocity comparison, while also showing limits at the highest tested velocity.

A preprint presents an implicit neural representation for designing three-dimensional point-spread functions. The reported tests included rotating helixes, an extended-depth-of-field pattern and multifocal designs, but the evidence is qualitative and limited to a described optical setup.

A computational study of high-harmonic generation in thin silicon slabs found that propagation depth and observation geometry changed the modeled spectrum. An alternative propagation method agreed with the full Maxwell calculation in some low-order cases but produced a model-sensitive high-order cutoff.
