longitudinal_misalignment_loss_db

ofiber.cylinder_step.longitudinal_misalignment_loss_db(n1, w, D, lambda0)[source]

Calculate the loss due to longitudinal fiber misalignment.

See Ghatak eqn 8.81

Parameters:

  • n – index between fiber ends [-]

  • w – mode field radius [m]

  • D – longitudinal fiber separation [m]

  • lambda0 – wavelength in vacuum [m]

Returns:

longitudinal misalignment loss dB [-]
