All-Chalcogenide Raman-Parametric Laser, Wavelength Converter, and Amplifier in a Single Microwire
Bibliographic record
Abstract
Compact, power efficient, and fiber-compatible lasers, wavelength converters, and amplifiers are vital devices for the future of fiber-optic systems and networks. Nonlinear optical effects, like Raman scattering and parametric four-wave mixing, offer a way to realize such devices. Here, we use a single chalcogenide microwire to realize a device that provides the functions of a Stokes Raman-parametric laser, a four-wave mixing anti-Stokes wavelength converter, an ultra-broadband Stokes/anti-Stokes Raman amplifier and a supercontinuum generator. The device operation relies on ultrahigh Raman and Kerr gain that are up to five orders of magnitude larger than in silica fibers, precisely engineered chromatic dispersion, and high photosensitivity of the chalcogenide microwire. Owing to the underlying principle of nonlinear optical processes, the device is anticipated to operate over the entire transmission window of the chalcogenide glass (λ ~ 1-10 μm).

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.
