From: Determination of mode strengths in channel waveguide from the complex electric field
Retrieved modal strengths and output field profile from a silicon nitride waveguide, where we consider only TE modes. (a) Measured (blue) and retrieved (red) intensity profiles of the total field at the output plane of the waveguide, (b) retrieved mode strengths (blue) and phases (red), (c) measured, and (d) retrieved absolute CSD. The first two modes have the highest contribution. The error bars correspond to one standard deviation.
