Abstract
This article presents a method for integrating traveling wave models (TWMs) into an optical circuit simulator based on modified nodal analysis (MNA) techniques previously developed for electrical circuit simulation. TWMs of optical propagation through waveguides provide flexible distributed descriptions of optical devices from simple waveguides to lasers. The model is, however, by definition an explicit time marching method and does not fit naturally into an MNA formulation. This article will show a method of integrating the TWM into a fully implicit multidomain (electrical/optical) circuit simulator based on MNA techniques. It will first describe the TWM for simple optical propagation and then its extension for optical gratings, amplifiers, and lasers. The integration of the TWM model into the MNA-based engine will then be specified, showing how the model is implemented using nonlinear optical sources. Finally, a set of examples, including waveguides, filters, and electro-optic devices will be used to show the effectiveness of the technique.

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 it
