A photonic IC, laser diode and SOA simulator

PICWave Circuit Capabilities

The simulation of a photonic circuit includes two stages:

  1. Creating models of the individual circuit components

  2. Importing the individual component models into a standard circuit model format, connecting the components together and simulating the resulting circuit.

PICWave is primarily focussed on Stage 2, but also has the capability of modelling many components itself; in particular it has an extensive modelling capability of semiconductor gain sections (SOAs). 

PICWave has a building block system allowing you to create your own libraries of pre-made components, or use design kits provided by a third party; we currently supply InP-based design kit libraries for Smart Photonics and FhG Heinrich Hertz Institut fabs. Others coming soon. Please ask.

The table below describes PICWave's capabilities in terms of circuit, component and material modelling, and its reliance on external models (such as FIMMPROP and Harold).
