LP_mode_value

ofiber.cylinder_step.LP_mode_value(V, ell, em)

Calculate guided b for mode (ell,em) in a circular step-index fiber.

b is the normalized propagation constant. Each guided mode in an optical fiber has a specific value of b that depends on the fiber parameter V and the mode numbers ell and em.

This is a wrapper function that handles V, ell, or em being possible arrays. See LP_mode_value for details.

Parameters:

• V – V-parameter for optical fiber [-]

• ell – primary fiber mode (integer) [-]

• em – secondary fiber mode (integer>0) [-]

Returns:

guided normalized propagation constant for mode (ell,em) [-]
