Infrared Performance of Symmetric Surface-Plasmon Waveguide Schottky Detectors in Si
Bibliographic record
Abstract
The internal quantum efficiency, responsivity, and sensitivity of symmetric surface-plasmon waveguide Schottky detectors in silicon are investigated theoretically at room temperature at λ0= 1310 and 1550 nm. The detectors consist of a thin metal stripe buried in Si, forming Schottky contacts along all metal/Si interfaces, with detection occurring via internal photoemission over the Schottky barriers. Several metals are considered for the stripe (Au, Ag, Al, Cu, CoSi2). The internal quantum efficiency is significantly enhanced for stripes that are thin compared to the hot carrier attenuation length. Responsivities of 0.1 to 0.21 A/W and receiver sensitivities of -24 and -18 dBm are predicted for 1.5 and 10 GHz electrical bandwidths (~2.5 Gbit/s and >; 10 Gbit/s), respectively. This predicted performance, at room temperature, is competitive with the best cryogenically cooled conventional Schottky detectors and is adequate for optical interconnect and power monitoring. The detectors are attractive for applications requiring broadband (electrical and optical) infrared detectors in Si.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
