Fraunhofer HHI Delivers Its First SOA Compact Model with Ansys
Highly integrated photonic systems are necessary to meet demanding power and performance targets
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.
