P. Lusse et al., COMPARISON OF A VECTORIAL AND NEW SEMIVECTORIAL FINITE-DIFFERENCE APPROACH FOR OPTICAL WAVE-GUIDES, Optical and quantum electronics, 29(2), 1997, pp. 115-120
In this article, a new semivectorial finite-difference method is prese
nted. By comparing the results obtained by the new approach with a vec
torial method, it is shown that the accuracy is still very high with c
osts reduced by a factor of two.
