angular_misalignment_loss_db

ofiber.cylinder_step.angular_misalignment_loss_db(n, w, theta, lambda0)[source]

Calculate the loss due to angular fiber misalignment.

See Ghatak eqn 8.75

Parameters:

  • n – index between fiber ends [-]

  • w – mode field radius [m]

  • theta – angular misalignment [radians]

  • lambda0 – wavelength in vacuum [m]

Returns:

angular misalignment loss in dB [-]
