Adiabatic taper

[lukasc-ubc]

Create an "adiabatic taper" based on the paper: https://doi.org/10.1364/PRJ.2.000A41

This requires an implementation of equation 2 which can be done in KLayout:

theta (x) = lambda / 2 W n_eff

n_eff (W): We could write an effective index method n_eff calculation, or call Lumerical MODE to provide it the sweep data.

Draw the structure based on a value alpha provided by the user.

Create an INTERCONNECT component with matching parameters; call 3D-FDTD and auto-generate the S-Parameters and add it to the library.
