regenerate_ybranch

si_fab.components.y_branch.regeneration.regen_utils.regenerate_ybranch(ybranch_class, wavelengths, center_wavelength, resimulate=True, plot=True)

It regenerates the simulation fitting data and/or the plots of the optimized Y-splitter.

Parameters:

ybranch_class

PCell class of the Y-branch to resimulate or replot

wavelengthstuple

Tuple representing the wavelength range for the simulation and for the plots. The tuple must be in the format (min, max, number of points).

center_wavelength: float

The center wavelength around which to have polynomial fitting

resimulateboolean, optional, default=True

If True, it runs the Lumerical FDTD simulation of ysplitter_class, fits the transmission and reflection as a function of wavelength and stores the fitting coefficients in data/component_name.json

plotboolean, optional, default=True

If True, it plots the transmission and reflection as a function of wavelength.
