Abstract grating coupler.

Based on TwoPortModel. Constant-phase, lumped model. Port 0 is the fiber side and port 1 is the waveguide side.

Args

  • insertion_loss: Total insertion loss.
  • return_loss_fiber: Return loss seen from the fiber side.
  • return_loss_wg: Return loss seen from the waveguide side.
