Determination of guided-mode resonances in photonic crystal slabs
Bibliographic record
Abstract
We present a design and analysis study of guided-mode resonances in photonic crystal slabs. Three-dimensional finite-difference time-domain (FDTD) simulations are used in parallel with a simplified model of guided-mode resonances to produce a representation of their evolution with structural parameters. From the analysis of the effective medium behavior of the system, we propose a simplified method able to predict the first guided-mode resonances at normal incidence with a good accuracy (∼1%) for holes with radius-to-period ratio smaller than 0.3 for the transverse magnetic polarization created internally. A substantial gain of time is, therefore, provided compared to FDTD (from the hours level to the seconds level). We also focus on two other important parameters, the quality factor and asymmetry of peaks, and present a way to design symmetric peaks with low sidebands.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
