Abstract
Abstract The TLM‐based FDTD method is extended to the modelling of optical bistability caused by the saturable Kerr‐effect of a GaAs–GaAsAl multiple quantum well (MQW) like medium. This structure is one of the possible candidates to be used as an all‐optical switch in high‐speed communication systems. The purpose of this paper is to demonstrate the capability of the TLM‐based FDTD method in handling the non‐linear medium problems, by performing a time‐domain simulation starting from the basic equations that represent the problem. A recursive formulation is derived to account for the saturable Kerr properties of the material and a physically realizable Fabry–Perot cavity is simulated. The numerical results confirm the effectiveness of the TLM‐based FDTD method for bistability modelling, and thus provide the foundations for further work and the simulation of more complicated and realistic bistable structures promising for high‐speed all‐optical digital signal processing.

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.
