waveguide
waveguide#
- waveguide(wl: Union[float, jax.Array] = 1.55, pol: Literal['te', 'tm'] = 'te', length: float = 0.0, width: float = 500.0, height: float = 220.0, loss: float = 0.0) Dict[Tuple[str, str], jaxtyping.Complex[Array, '...']][source]#
Model for an waveguide optimized for TE polarized light at 1550 nanometers.
A waveguide easily connects other optical components within a circuit.
- Parameters
pol (str, optional) – Polarization of the grating coupler. Must be either ‘te’ (default) or ‘tm’.
length (float, optional) – Waveguide length in microns (default 0).
width (float, optional) – Waveguide width in nanometers (default 500).
height (float, optional) – Waveguide height in nanometers (default 220).
loss (float, optional) – Loss of the waveguide in dB/cm (default 0).
sigma_ne (float, optional) – Standard deviation of the effective index for monte carlo simulations (default 0.05).
sigma_ng (float, optional) – Standard deviation of the group velocity for monte carlo simulations (default 0.05).
sigma_nd (float, optional) – Standard deviation of the group dispersion for monte carlo simulations (default 0.0001).
Notes
The sigma_ values in the parameters are used for monte carlo simulations.
