# 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.  

## Dataset Structure 🏗️
Each row corresponds to a **single simulation or measurement configuration** for a waveguide, including:

1. **Material Properties**  
   - `waveguide_material`: Core material (e.g., Silicon Nitride).  
   - `cladding_material`: Cladding material (e.g., Silicon Dioxide).  

2. **Waveguide Dimensions**  
   - `waveguide_width` (µm): Width of the waveguide core.  
   - `waveguide_height` (µm): Height of the waveguide core.

3. **Thermal Parameters**  
   - `temperature_min` (°C): Minimum temperature.  
   - `temperature_max` (°C): Maximum temperature.  
   - `temperature_step` (°C): Increment for simulations.  
   - `thermal_expansion_coefficient` (1/K): Expansion due to temperature.  
   - `thermal_conductivity` (W/m·K): Heat transfer ability.

4. **Optical Performance**  
   - `refractive_index_core` and `refractive_index_cladding`: Core and cladding indices at room temperature.  
   - `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.  
   - `optical_power_input` (mW): Power at waveguide input.  
   - `optical_power_output_min` and `optical_power_output_max` (mW): Output power at temperature limits.  

6. **Simulation and Metadata**  
   - `wavelength_min` and `wavelength_max` (nm): Operating wavelength range.  
   - `simulation_model`: Method used (e.g., FEM, FDTD).  
   - `measurement_uncertainty` (%): Error margin.
