Dataset supporting the paper "Stable non-volatile phase modulation with antimony-based phase shifter on broadband silicon nitride platform"

This dataset supports the manuscript titled;
"Stable non-volatile phase modulation with antimony-based phase shifter on broadband silicon nitride platform."

It includes data from both simulations and experimental measurements, used to generate the figures in the manuscript:

Figure 1(c) and 1(d): Data obtained from Lumerical simulations related to the geometrical optimization of tapers.

Figure 3(b): Experimentally measured propagation loss for both amorphous and crystalline phase-change material (PCM) states, using the cutback method. Optical phase shifter (OPS) lengths range from 20 µm to 80 µm in 20 µm increments.

Figure 3(c): Transmission spectra over three phase-transition cycles (SET and RESET pulses). Data is organized into six sheets, each corresponding to a specific cycle and pulse type.

Figure 4(a): Experimentally recorded temporal response of the device under SET and RESET electrical pulses.

Figure 4(b): Experimentally measured extinction ratio of the device over 7,900 phase-change cycles.

Figure 5(a): Simulated temperature distribution along the PCM layer, extracted from COMSOL Multiphysics.

Figure 5(b): Top-down COMSOL simulation showing the temperature profile across the device.

The dataset is provided in Excel format and is intended to support transparency, reproducibility, and further analysis of the results presented in the manuscript.
