Optical Absorption Simulation

Features

• Dual simulation modes for different experimental needs
• Comprehensive material library(more to be added) with composition control
• Advanced Drude model parameter adjustment
• Experimental data import and comparison tools

Operation Modes

1. Standard Configuration

Structure:

1. Metal Contact (adjustable Drude parameters)
2. DBR Stack (alternating layers)
3. Active Layer
4. Substrate

Drude Parameters: 'f0' = Oscillator strength 'γ0' = Damping coefficient [eV] 'ωp' = Plasma frequency [eV]

2. Manual Configuration

Customization Options:

• Layer-by-layer structure design
• Material selection from library
• Composition adjustment for alloys
• Thickness control for each layer

Example Workflow:

1. Add substrate layer (e.g., GaAs)
2. Add active layers (e.g., AlGaAs QWs)
3. Add top contacts (e.g., Au/Ti)
4. Set measurement parameters
