Abstract
A new approach to electro-optic (EO) detection is demonstrated through a novel geometry, whereby the probe and terahertz electric fields propagate in opposite directions. Theoretical analyses and experimental measurements are performed using a representative ZnGeP<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> crystal implemented within this backward EO detection configuration. The backward EO detection signals encompass frequencies within a narrow spectral band of a few hundred gigahertz, tunable from ∼0.6–2.4 THz through adjustment of the incidence angle of the electric fields relative to the EO crystal. This novel arrangement provides EO detection with new phase-matching possibilities and offers a powerful tool for narrow-band spectroscopy.

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
