hcipy.mode_basis.make_LP_modes(grid, V_number, core_radius, return_betas=False)¶ Make a ModeBasis out of the guided modes that are supported by a step-index fiber.
This function solves the eigenvalue equation of for a radial step-index profile fiber. It calculates the mode profiles and can also return the propagation constants.
- Parameters
- gridGrid
The grid on which to calculate the mode basis.
- V_numberscalar
The normalized frequency parameter of the fiber.
- core_radiusscalar
The core radius of a step-index fiber.
- return_betasbool
If true this function also returns the propagation constants.
- Returns
- ——-
- ModeBasis
An ModeBasis containing all supported LP modes.
- array_like
An array containing all propagation constants. This is only returned if return_betas is True.
