Abstract

fetched live from OpenAlex

A theoretical and experimental analysis of an all-optical polarization switching technique that has been demonstrated recently is presented. The analysis is restricted to the lowest-order nonlinear regime (${\ensuremath{\chi}}^{(3)}$ regime). The theory allows for a detailed analysis of the switching action, which is based on near-resonant optical excitation of spin-polarized excitons. The theoretical results are found to be in good agreement with experimental data. The respective contributions of phase-space blocking and various many-particle interaction and correlation terms to the switching process are identified and studied as function of experimentally adjustable parameters. The resulting parametric dependence of the switching action is used as a basis for proposals for further optimization of the device.

Full frame distilled prediction

Teacher imitation

Not 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.
