Towards compact photonic devices in highly nonlinear chalcogenide microwires
Bibliographic record
Abstract
The future of fiber optic systems lies in the development of all fiber photonic devices thatare compact, power efficient, and can provide novel functionalities. Here, we propose anddemonstrate the realization of such photonic devices using chalcogenide microwires. Thedevices include Bragg gratings, wavelength converters, broadband amplifiers and lasers. Thedevices' operation relies on the ultrahigh nonlinear optical gain (>5 orders of magnitudelarger than in silica fibers) and the high photosensitivity of chalcogenide microwires. Theresulting photonic devices are a few centimeters in length, a few micrometers in diameter,and operate at record-low optical power levels (i.e., in the order of a few hundreds of microWatts). In addition, chalcogenide glasses are transparent over an ultrabroad wavelengthrange (1-10 microns in wavelength), making these devices capable of operation in the midinfraredwavelength region. Such photonic devices have been realized for the first time insuch a compact and power efficient geometry, and are thus leading candidates for replacingtheir electronic counterparts. The devices are applied with a polymer coating to add physicalstrength and for protection against any environmental damage. Owing to their compactness,power efficiency and ultra broadband operation window, these novel photonic devicescarry great commercial and research value for a wide range of fields, including biomedicine,instrumentation and mid-infrared spectroscopy.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
