HI,
I try to simulate the propagation of light in one waveguide. So I need to give out the transverse profile of source. I do it by hard source. The transverse profile is really tailored. However, the source introduce some diffracting in all directions because it is confined in transverse direction.
I know the popular bootstrapping method. It is used to find the transverse profile but not to eliminate the diffraction.
Could some body tell me how to introduce some transverse mode of a waveguide without this problem: the source diffract in any direction?
Thanks.
