Several commercial computer codes which strongly help the design of integrated optical devices are available on market: they are very versatile and powerful tools. However, the modelling via home-made computer can be advantageously employed in many niche investigations, to reduce the computation cost in the design of particularly complex structures. A hybrid approach is often the best trade-off solution. Here, as examples, the application of FEM/CMT methods has been illustrated with reference to SH generation and to evanescent field sensors but also to simulate rare-earth-doped micro-disks.
