The Kallistos module adds powerful automatic optimisation to your CrystalWave design suite. It will save you many hours of design time if not days and will often locate new designs that you are unlikely to obtain manually by trial and error. You can readily find global optima for 3 or 4 parameters of your choice or local optima for 10 or more. Photon Design has used this internally to develop photonic crystal components with World record efficiencies. 

The module provides several optimisation algorithms for you to choose from including both global and local. It also permits you to define your design goal (objective function) in a near-arbitrary manner, including use of multi-wavelength optimisation to locate wide bandwidth designs.

The tool includes advanced visualisation and interaction tools to communicate the large amounts of data generated to you and ensure that your insights as a designer can be enhanced rather than replaced by the automation process. Go to Kallistos for more details.
