Simulation and implementation of photonic integrated circuits for the filtering and optical heterodyning of mode-locked comb-lines
Bibliographic record
Abstract
We present the simulation and implementation of a photonic integrated circuit (PIC) designed for the filtering and optical heterodyning of comb-lines generated by a 20.97 GHz mode-locked fiber ring laser emitting at the optical C-band. We compare simulations obtained for the coupling junction of the microrings in the PIC with the use of an analytic approach and the finite difference time-domain (FDTD) method. A PIC designed for fabrication with the Triplex asymmetric double-stripe (ADS) waveguides was demonstrated. Using the PIC, we demonstrated the optical heterodyning of pairs of comb-lines filtered by tunable microrings. The phase noise of beat signals located at 20.97 and 41.94 GHz was characterized. We provide a discussion on enhancing the RF power of the beat signals with the use of optical injection locking.

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.
