Low-Loss Switchable Metasurface-Based Waveplate using Phase Change of Antimony Triselenide for Telecom Applications
Bibliographic record
Abstract
In this paper we introduce the design of a switchable metasurface waveplate using low-loss phase-change material. The structure includes Antimony Triselenide grating deposited over a glass substrate, which can be easily fabricated using standard silicon fabrication technology. By employing the different birefringent effect induced, the grating operates as a quarter-wave plate when Antimony Triselenide is in the amorphous state, and operates as a half-wave plate when it is in the crystalline state. The grating parameters (thickness, height, and period) are optimized using global genetic algorithm. The design provides above 80% transmission for amorphous and crystalline states over the telecom band between 1.3 and 1.65 µm. The proposed design constitutes an important device for integrated silicon nanophotonics and flat optics applications.

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.
