Thermal Stability Dataset 🔥❄️

Description
This dataset provides 100,000 synthetic rows of data for analyzing thermal stability in photonic waveguides. It tracks key parameters, such as material properties, optical losses, and refractive index changes under varying thermal conditions. Ideal for simulation and optimization of photonic devices.

Key Highlights ✨

• Focus: Thermal behavior of waveguides under varying environmental conditions.
• Columns: 26 structured columns capturing material properties, geometric dimensions, and thermal-optical effects.
• Size: 100,000 rows suitable for training machine learning models or validating designs.
• Use Cases:
  • Thermal stability analysis for waveguides and photonic chips.
  • Thermo-optic device optimization.
  • Simulation of thermal crosstalk in integrated photonic systems.

   • propagation_loss_min and propagation_loss_max (dB/cm): Losses at min and max temperatures.
   • effective_index_min and effective_index_max: Mode index at temperature limits.
   • dn_dT (1/°C): Change in effective index with temperature.
   • thermal_tuning_efficiency (%): Efficiency of thermal tuning.

5. Environmental and Operational

   • thermal_stress (MPa): Stress induced by temperature changes.
   • strain_rate (1/°C): Dimensional changes per degree.
