Summary and References
ZEMAX has comprehensive fiber modelling capabilities.
- The simplest method, a paraxial Gaussian beam is useful to get a feel for the system and to understand its first-order properties.
- The ray-based Fiber Coupling calculation is useful where the fiber modes are Gaussian, and diffraction effects are negligible.
- Physical Optics provides a comprehensive solution to modelling fiber coupling, allowing any complex mode to be used as source or receiver fiber, with full treatment of diffraction effects.
- The effects of thin-film coatings and material absorption can also be included.
- Optimization of these systems is straightforward with the FICL and POPD operands
- Tolerancing can be achieved using the same merit function operands as optimization.
