Bottle micro-resonator temperature sensors for laser coolers
Bibliographic record
Abstract
We show theoretically that a bottle resonator with a nanoscale altitude made on the surface of an optical fiber can be used as a temperature sensor for laser cooling of solids. The operation of such sensors is based on whispering gallery modes (WGMs). Bottle resonators can be made at different positions along the length of the fiber, which undergoes laser cooling. A smooth perturbation with a small nanoscale altitude on the surface of the fiber does not couple fiber modes propagating along the fiber axis and does not influence the laser cooling process. The temperature of the sample at each of these positions can be monitored as a shift in the dips seen in the transmission spectrum of a biconically tapered fiber placed perpendicular to the fiber axis on the top of the resonator to excite WGMs. Temperature sensitivities ~12pm/K and ~16pm/K are obtained for Yb<sup>3+</sup>:ZBLAN and Yb<sup>3+</sup>:YAG samples, respectively. The possibility of using bottle resonators for other applications is also discussed.

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.
