3.2.3.17. lekkersim.TH_PhaseShifter

class lekkersim.TH_PhaseShifter(L: float, Neff: Callable, R: float = None, w: float = None, wl: float = None, pol: int = None, param_name: str = 'PS')

Model of thermal phase shifter (dispersive waveguide + phase shifter)

__init__(L: float, Neff: Callable, R: float = None, w: float = None, wl: float = None, pol: int = None, param_name: str = 'PS') → None

Initialize the model

Parameters:

  • L (float) – length of the waveguide

  • Neff (function) – function returning the effective index of the wavegude. It must be a function of wl,R,w, and pol

  • wl (float) – default wavelength of the waveguide

  • w (float) – default width of the waveguide

  • R (float) – default bending radius of the waveguide

  • pol (int) – default mode of the waveguide

  • param_name (str) – name of the parameter of the Phase Shifter
