D. Yevick, A GUIDE TO ELECTRIC-FIELD PROPAGATION TECHNIQUES FOR GUIDED-WAVE OPTICS, Optical and quantum electronics, 26(3), 1994, pp. 190000185-190000197
We summarize field propagation techniques for fibre and integrated opt
ics with emphasis on fast Fourier transform, finite-difference, finite
-element and Lanczos methods for both paraxial and wide-angle calculat
ions.
