Analysis of fiber-grating-coupled semiconductor lasers for WDM applications
Bibliographic record
Abstract
A novel external-cavity geometry for a semiconductor laser can be constructed by coupling the laser light through an antireflection coating on the laser diode face into a fiber, some distance along which a Bragg grating is written in the fiber core. The grating forms one mirror defining the cavity, a high reflectivity coating on the back end of the diode serving as the other mirror. After reviewing the work in this area, we will turn to cw operation, where in certain circumstances the stability against mode hopping has been observed to depend on the chirp of the Bragg grating. A simple physical picture of such behavior is possible because the cavity round trip time is much greater than the transit time of the light in the gain medium. This picture will be outlined, and used to explore the range of behavior possible when the laser is directly modulated. Recent theoretical and experimental studies focusing on applications for wavelength-division multiplexing will be discussed.

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.
