difference formula. The problem is that the curve I get is the same as bulk
silica. I made lots of changes to the fiber profile loaded, and couldn't get
any of those to resemble the real fiber dispersion.
First make sure you are looking at the correct mode. Run
output-poynting-z or similar to look at the field and dielectric profiles,
to make sure it is what you expect.
Second, make sure you don't have some units problem in your Silicon_eps
function that is causing the material dispersion to be much larger than it
is supposed to be (and therefore to dominate) relative to the waveguide
dispersion. Be cautious about the usual confusions about 2pi factors
etcetera.
Cordially,
