Silicon-on-Insulator In-Plane Gires–Tournois Interferometers
Bibliographic record
Abstract
Gires–Tournois interferometers (GTIs) based on deep-etched silicon-air Bragg mirrors and on optical quality dicing of silicon are reported. Broadband reflectivity of the deep-etched Bragg mirrors allows operation on a wavelength range exceeding the C Band window. The waveguided in-plane configuration of the devices allows interferometer lengths that are not typically achievable on chips using out-of-plane designs (e.g., <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$L>1~{\rm mm}$</tex></formula> for a 25-GHz free spectral range). Optical characterization of GTIs having two different free spectral ranges (i.e., 25 and 100 GHz) yield off-resonance insertion losses below 2 dB and polarization-dependant losses (PDL) below 1 dB. Insertion losses and PDL are, however, more important near the resonance wavelengths, reaching, respectively, 15 and 5 dB. Calculations show that the reported devices could be useful for Michelson-GTI bandpass filters, such as optical interleavers.

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.
