Abstract

fetched live from OpenAlex

A novel uni-traveling-carrier photodetector (UTC-PD) structure with an integrated focusing-reflection (FR) mirror realized by a non-periodic concentric circular high-contrast grating, referred to as FR-UTC-PD, is proposed to enhance responsivity in conventional UTC-PDs. The FR-UTC-PD allows us to improve the responsivity by 36.5% at a 1.55 μ m wavelength as compared to a UTC-PD without integrated an FR mirror with 84.59% reflectivity. For 40 μ m diameter PDs, the obtained 3 dB bandwidths are unaltered with values of 18 GHz at −3.0 V bias voltage. The radio-frequency output power and photocurrent are −1.77 dBm and 17.56 mA, respectively, at 10 GHz and the −6.0 V bias voltage.

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.
