Optomechanical cavities in silicon-on-insulator
Bibliographic record
Abstract
Integrated optomechanical cavities allow precise control of optical and mechanical modes and enable strong photonphonon interactions in micron-scale volume, key for the implementation of microwave-photonic oscillators and quantum transducers. Silicon photonics provides low production cost and compatibility with the state-of-art optoelectronic circuitry. Thus, it is particularly interesting for the implementation of on-chip optomechanics. However, silicon has higher stiffness and acoustic velocity than the silica cladding, hampering phonon confinement in silicon-on-insulator (SOI) waveguides. Here, we present our most recent results on SOI optomechanical systems coupling mechanical and guided optical modes. The cavities use silicon pillars with subwavelength period. Strong radiation pressure is exploited to drive the optomechanical coupling. Based on this concept, we experimentally demonstrate the optomechanical coupling between photons and high-quality factor phonons in non-suspended cavities, with a great potential for applications in quantum and classical photonics.

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; both teacher heads agree on what is shown here.
