High index glass CMOS compatible all-optical chips for telecom and optical interconnects
Bibliographic record
Abstract
This paper reports a wide range of functions in a CMOS compatible high index doped silica glass platform, including an integrated multiple wavelength source, an ultra-high repetition rate modelocked laser, and an all-optical integrator. CW oscillation in a Q =1.2 million micro-ring resonator with a slope efficiency of 7.4% (single oscillating mode, single port), a threshold power of 54 mW, and frequency spacings from 200 GHz to >; 6THz was achieved as well as modelocking with repetition rates as high as 800GHz. Novel functions in ultra-long (45cm) spiral waveguides, including a time-lens optical oscilloscope and parametric amplifier with >; 15dB of gain is also reported. The success of these devices is due to very low linear loss, negligible nonlinear loss (up to 25GW/cm2), and a high γ = 233W-1km-1. The low loss, design flexibility, and CMOS compatibility of this platform will enable devices for telecommunications, computing, sensing, metrology and other areas.

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.
