Normalized frequency (fiber optics)
text:
In an optical fiber, the normalized frequency, V, is given by V = 2 π a λ n 1 2 − n 2 2 = 2 π a λ × N A, where a is the core radius, λ is the wavelength in vacuum, n1 is the maximum refractive index of the core, n2 is the refractive index of the homogeneous cladding, and applying the usual definition of the numerical aperture NA. In multimode operation of an optical fiber having a power-law refractive index profile, the approximate number of bound modes, is given by V 2 2 , where g is the profi
