Broadband, high-linearity TFLN electro-optic modulator for integrated microwave photonics using reconfigurable dual-parallel modulation
Bibliographic record
Abstract
Integrated electro-optic modulators with large bandwidth, high linearity and low driving voltage are key building blocks for integrated microwave photonic (IMWP) links to transmit broadband signals with high fidelity. In this work, thin-film lithium niobate electro-optic modulator consisting of a thermo-optic reconfigurable coupler and dual-parallel Mach-Zehnder modulation scheme is proposed and demonstrated to achieve spurious-free dynamic range of 112.87/107.71 dB·Hz 2/3 at 1/10 GHz while keeping large bandwidth (>67 GHz) and low half-wave voltage (2.7 V) simultaneously. The demonstration of this device paves a new route for high-performance electro-optic modulators in future functional IMWP systems.

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.
