Abstract phase modulator.

Based on PhaseModTimeStepper.

Args

  • length: Physical length of the modulator segment.
  • n_eff: Effective index of the optical mode at the reference frequency.
  • n_group: Group index of the optical mode, used to calculate delay.
  • reference_frequency: Reference frequency for the effective and group indices.
  • v_piL: Electro-optic phase coefficient VπLV_{\pi L}.
  • z0: Characteristic impedance of the electrical port used to convert the input field amplitude to voltage.
  • propagation_loss: Optical propagation loss.
  • k2: Quadratic nonlinear phase coefficient.
  • k3: Cubic nonlinear phase coefficient.
  • dloss_dv: Linear voltage-dependent optical loss coefficient.
  • dloss_dv2: Quadratic voltage-dependent optical loss coefficient.
  • f_3dB: -3 dB frequency cutoff for bandwidth limiting. Only active for positive values.
