Ansys Lumerical MQW
Quantum Well Gain Simulator

Ansys Lumerical MQW simulates quantum mechanical behavior, allowing you to accurately characterize band structure, gain and spontaneous emission in multi-quantum well structures.

SOLVE THE UNSOLVABLE Lumerical MQW calculates optical and electronic properties of multi-quantum well stacks

Simulating quantum mechanical behavior in atomically thin semiconductor layers enables you to accurately characterize band structure, gain and spontaneous emission across multi-quantum well structures. MQW couples to Lumerical CHARGE, MODE and INTERCONNECT to enable design of lasers, SOAs, electro-absorption modulators, and other gain-driven active devices.

BUSINESS BENEFITS

With the ability to import compact models, use Ansys INTERCONNECT to design and simulate circuits with SOA. Use Lumerical MQW to design custom lasers and gain elements.

The development of compact and efficient SOAs is a current focal point for the photonics industry. There is a need for system-level models calibrated to foundry measurements that enable engineers to leverage custom SOAs at the circuit level with the confidence their manufactured circuit will work as expected. The availability of compact models for SOAs has been limited by the complexity of the physics involved and the challenge of solving the problem efficiently. With a compact model that has been parameterized to HHI’s foundry now available, designers can avoid the costly effort of parameter extraction and calibration. The foundry-calibrated model gives designers flexibility while saving them the time and cost of iterations usually associated with customized advanced devices.
