Quantum Well Gain Simulator
MQW simulates quantum mechanical behavior in atomically thin semiconductor layers, enabling engineers to accurately characterize band structure, gain and spontaneous emission in multi-quantum well structures. When designing lasers, SOAs, electro-absorption modulators or other gain-driven active photonic devices, MQW provides the deep physical insight necessary to ensure success.
MQW is a solver within Lumerical’s DEVICE Multiphysics Simulation Suite, the world’s first multiphysics suite purpose-built for photonics designers. The DEVICE suite enables designers to accurately model components where the complex interaction of optical, electronic, and thermal phenomena is critical to performance. As part of Finite Element IDE, designers can quickly analyze complex active devices while benefiting from Lumerical’s industry-leading usability, performance, and accuracy.
Key MQW applications include:
- edge-emitting lasers
- Electro-absorption modulators
- Fully-coupled quantum mechanical band structure calculation using k.p method
- Wavefunction and band diagram calculation
- Gain and spontaneous emission
- Incorporates temperature, field, and strain effects
Integrated Laser Simulation
- Simulate and extract key parameters for TWLM
- Build sophisticated laser models, incorporating tuning and external feedback effects
- Characterize steady-state and transient laser performance, including threshold gain, lasing spectrum, SMSR, LI, turn-on, and modulation response
- Requires INTERCONNECT and Laser Element Library licenses
Comprehensive Material Models
- Includes material library with common III-V semiconductors
- Automatically builds models for fractional semiconductor alloys (eg. InGaAsP)
- Script accessible and customizable
Lumerical tools are interoperable through the Lumerical scripting language, Automation API, and Python and MATLAB APIs.
