Abstract

fetched live from OpenAlex

A high extinction ratio modulator using the epsilon-near-zero (ENZ) material of cadmium oxide (CdO) is proposed. The proposed device consists of a shoulder-coupled cavity at the middle of a photonic crystal (PC) structure where input light is coupled through a PC line defect waveguide. The shoulder-coupled resonant cavity is infiltrated with high mobility CdO. The structure is simulated by the two-dimensional finite-difference time-domain method. According to the presented results, a high extinction ratio of 21.32 dB as well as a low insertion loss of 0.22 dB around the operating wavelength of 1.55 μm are achieved when a low voltage of 3.18 V is applied to the ENZ material. The modulation speed is as high as 14.4 GHz. Owing to the high quality-factor resonance of 1244, a strong field localization in the microcavity is obtained. The proposed modulator based on the high-mobility ENZ material of CdO could have a promising impact on future optical communications systems.

Teacher imitation

Not 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.
