The fiber_array photonic model represents a parameterized multi-fiber array, enabling users to model the chip-to-fiber or fiber-to-chip coupling loss after packaging (the 3DIC) in photonic circuit simulations. The model supports an arbitrary number of ports as well as design parameters and can be statistically enabled. Each design parameter of the multi-fiber array can be converted into a statistical parameter for performing yield analysis. For information on statistical CMLs, see Statistical CMLs.

Model Information
This model supports an arbitrary number of input and output optical ports.
This model supports an arbitrary number of ‘nominal’ design parameters. The user provided design parameters are shared by all the channels (fiber – waveguide pairs).
Each ‘nominal’ parameter can have a corresponding statistical parameter. The statistical parameters are duplicated during the model building process and each channel gets their own set of statistical parameters.
In a Monte-Carlo simulation, the randomly generated statistical parameter values get added to the nominal parameter value for each channel.
This model is currently insensitive to simulation wavelength and optical mode.
