Radiation Suppressing Metallo–Dielectric Optical Waveguides
Bibliographic record
Abstract
In this paper, a theoretical study of the optical performance of the parallel-plate waveguide, the nonradiative dielectric (NRD) waveguide, and a recently proposed metallo-dielectric waveguide (MDW) [Buckley and Berini, <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Optics</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Letters</i> , vol. 34, no. 2, pp. 223-225, 2009] is reported. One-dimensional analysis is used to gain insight into their operation, followed by full-wave 2-D simulations of the waveguides in their straight and curved form. The modes supported by the NRD waveguide are perturbed by the excitation of surface plasmon polaritons (SPPs) along the metal surfaces causing high propagation loss for the straight waveguide and mode deformation along radial bends, as r <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> rarr 0. In contrast the recently proposed MDW shows promise due to its ability to guide the fundamental TE mode over long-range ( ~ 1.2 dB/mm) and through aggressive bends with low loss while retaining its mode character. The waveguide also has potential use in optoelectronic/electrooptic components due to the presence of the metal plates.

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.
