Programmable On-Chip Photonic Signal Processor Based on a Microdisk Resonator Array
Bibliographic record
Abstract
A programmable on-chip photonic signal processor based on a silicon photonic microdisk resonator array is proposed and experimentally demonstrated. The processor has a two-dimensional mesh network structure with multiple input and multiple output ports. In each mesh cell, two identical thermally-tunable high-Q microdisk resonators (MDRs) are used for routing and processing the optical signal, and a low-loss waveguide crossing is employed at the waveguide intersection to enable low-crosstalk optical transmission. By programming the DC voltages applied to the MDRs, the processor can be reconfigured with diverse circuit topologies to perform multiple array signal processing functions. An 8 × 8 programmable signal processor is designed, fabricated and characterized. By controlling the DC voltages, an on-chip tunable optical delay line based on 8 MDRs cascaded in an all-pass filter configuration is experimentally demonstrated. Thanks to scalable mesh structure of the proposed processor, the entire device holds a promising potential for strong reconfigurability and parallel computing with low power consumption.

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.
