Deterministic-Frequency Optoelectronic Synthesizer Architecture Using Injection-Locked Oscillators
Bibliographic record
Abstract
Optoelectronic oscillators (OEOs) are widely used in high-precision radiofrequency (RF) signal generation due to their ultra-low phase noise characteristics. However, conventional OEOs suffer from unpredictable startup frequencies, leading to inconsistencies in practical applications. Conversely, traditional RF oscillators exhibit deterministic startup frequencies but are inherently limited by higher phase noise. This paper presents a novel OEO architecture that integrates an RF injection-locked oscillator (ILO) to overcome both challenges simultaneously. By leveraging the frequency-selective properties of the ILO, the proposed system ensures that the OEO consistently starts at a predefined frequency while maintaining its ultra-low phase noise. This advancement is critical for applications in high-precision timing, stable RF communications, and next-generation radar and sensing systems, where both frequency stability and spectral purity are paramount. Experimental results demonstrate that the proposed approach effectively locks the startup frequency with high precision while preserving the superior phase noise performance of the OEO. This breakthrough paves the way for more robust and reliable frequency-selective systems in advanced RF and photonic technologies.

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.
