"Tools and techniques for modeling the propagation of coherent fields, Fourier methods applied to Gaussian-beam decomposition, and the finite-difference beam-propagation method can help ensure accurate and efficient coupling. But all perspectives, from the macroscopic to the microscopic, must be considered.
Modeling the propagation of coherent fields, from the macroscopic (such as bulk optics) to the microscopic (such as guided optics) has typically involved two methods. For free-space propagation in bulk optics, Fourier methods have been applied to Gaussian-beam decomposition (GBD). For the guided-wave domain, methods based on finite-difference methods, either in time or space, can be employed. ..."
