Numerical Investigation of Mid-Infrared Supercontinuum Generation in GeAsSe Based Chalcogenide Photonic Crystal Fiber Using Low Peak Power
Bibliographic record
Abstract
We numerically investigate the use of photonic crystal fiber (PCF) through dispersion engineering of its cladding containing air-holes for supercontinuum (SC) generation in the mid-infrared region using low peak power. A 3.6-cm-long PCF made using Ge11.5As24Se64.5 chalcogenide (ChG) glass with a hexagonal array of air-holes was optimized for obtaining zero-dispersion wavelength through dispersion tailoring around the pump wavelength of 4 μm. We have performed numerical simulations for such dispersion tailored ChG PCF with the peak power range between 0.25 kW and 2 kW. It was found through rigorous numerical simulations that an ultrabroadband mid-infrared SC spectra covering the wavelength range 2-8 μm which is equivalent to 2 octaves could be generated using pump pulses of 320 fs duration at a wavelength of 4 μm with a relatively low peak power of 2 kW by using our proposed ChG PCF design.

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.
