Polarization‐Tuned Fano Resonances in All‐Dielectric Short‐Wave Infrared Metasurface
Bibliographic record
Abstract
Abstract The short‐wave infrared (SWIR) is an underexploited portion of the electromagnetic spectrum in metasurface‐based nanophotonics despite its strategic importance in sensing and imaging applications. This is mainly attributed to the lack of material systems to tailor light–matter interactions in this range. Herein, this limitation is addressed and an all‐dielectric silicon‐integrated metasurface enabling polarization‐induced Fano resonance control at SWIR frequencies is demonstrated. The platform consists of a 2D Si/Ge 0.9 Sn 0.1 core/shell nanowire array on a silicon wafer. By tuning the light polarization, it is shown that the metasurface reflectance can be efficiently engineered due to Fano resonances emerging from the electric and magnetic dipoles competition. The interference of optically induced dipoles in high‐index nanowire arrays offers additional degrees of freedom to tailor the directional scattering and the flow of light while enabling sharp polarization‐modulated resonances. This tunablity is harnessed in nanosensors yielding an efficient detection of 10 −2 changes in the refractive index of the surrounding medium.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
