Slow-light enhanced silicon photonic crystal phase tuner actuated by electrostatic comb drives
Bibliographic record
Abstract
This paper presents the design, fabrication, and experimental demonstration of a silicon photonic phase tuner that leverages slow-light effects in a suspended photonic crystal (PC) slot waveguide. The phase is tuned by electrostatic comb actuation which modulates the slot width within the PC defect thus achieving a high phase sensitivity enhancement relative to a conventional slot waveguide. The device is fabricated using a silicon photonic foundry process followed by post-processing steps to remove the oxide cladding and suspend the PC slot waveguide and electrostatic actuation combs. The design exhibits up to a 16-fold improvement in phase sensitivity, enabling sub-volt V π with a nominal slot width of 200 nm. A small actuation length of just 33 μ m results in a V π L of 20.13 V μ m. The results demonstrate phase tuning with complementary metal-oxide-semiconductor (CMOS) compatible core voltages for high density, high speed applications in silicon photonics, such as optical phased arrays and photonic accelerators.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
