# Frequency Dispersion Dataset 📡
> **Description**
> This dataset provides **100,000 synthetic rows** to model **frequency dispersion** in photonic waveguides. It includes essential parameters such as **group index**, **chromatic dispersion**, and **mode group delay** across varying wavelength ranges, enabling simulation and optimization of waveguide designs for optical chips.
## Key Highlights ✨
- **Focus**: Frequency-dependent behavior of waveguides, specifically for **optical chips**.
- **Columns**: 21 structured columns capturing wavelength ranges, material properties, dispersion metrics, and loss measurements.
- **Size**: 100,000 rows, suitable for training machine learning models, validating designs, and simulating performance.
- **Use Cases**:
- **Modeling dispersion effects** in optical communication systems.
- **Broadband photonic device design** for minimal dispersion.
- **Waveguide optimization** for real-world environmental conditions.
## Dataset Structure 🏗️
Each row corresponds to a **single configuration or simulation result** for a waveguide, including:
1. **Wavelength Range**
- `wavelength_min` (nm): Minimum operating wavelength.
- `wavelength_max` (nm): Maximum operating wavelength.
2. **Dispersion Metrics**
- `group_index_min` and `group_index_max`: Group index values at the wavelength limits.
- `chromatic_dispersion` (ps/nm·km): Quantifies dispersion over the wavelength range.
- `mode_group_delay_min` and `mode_group_delay_max` (ps/m): Signal delay per meter.
- `material_dispersion` and `waveguide_dispersion`: Separate contributions to total dispersion.
3. **Effective Index**
- `effective_index_at_min`: Effective refractive index at minimum wavelength.
- `effective_index_at_max`: Effective refractive index at maximum wavelength.
- `effective_index_change`: Change in refractive index across the range.
4. **Material Properties**
- `waveguide_material`: Core material (e.g., Silicon Nitride).
- `cladding_material`: Cladding material (e.g., Silicon Dioxide).
5. **Loss and Environmental Parameters**
- `propagation_loss_min` and `propagation_loss_max` (dB/cm): Losses at wavelength limits.
- `temperature` (°C): Operating temperature.
- `signal_bandwidth` (GHz): Signal bandwidth.
- `device_length` (mm): Waveguide length.
6. **Metadata**
- `measurement_method`: Method used for data collection (e.g., Optical Time Domain Reflectometry).
- `measurement_uncertainty` (%): Error margin in data.
