Optickle

Matlab model of optical cavities

It is a semi-analythical modeling package. The two building blocks of the models are a Fabry-Perot function and a Michelson function. Each function replaces either a cavity or a Michelson by with an effective compound mirror of which complex reflectance and transmittance are calculated. The input parameters are the most generic. The surfaces of all mirrors are treated individually, i.e. reflectance and transmittance can be set independently for each side of a mirror.

By nesting any combination of cavities in the proper way and order, one can build up a compound mirror representing the whole interferometer. Reflectivity and transmissivity of the compound mirror will be the Bright and Dark port outputs, respectively.

All functions contain a detailed help description.
