Experiment -2 AIM: Calculate for graded index fibers- a) Graphical representation of core refractive index n 1 [r] w.r.t. radius(a) of core for– i. Profile parameter(α) = 1 ii. Profile parameter(α) = 2 iii. Profile parameter(α) = ∞ b) Graphical representation of numerical aperture NA[r] w.r.t. radius of core (r) for – i. Profile parameter(α) = 1 ii. Profile parameter(α) = 2 iii. Profile parameter(α) = ∞ c) Acceptance Angle (θa) for given value of radius Where 0 < r <= a ∆ = refractive index difference Input required Boundary limits for inputs Formula Expected output Units n 1 [0] and n 2 1.4 < (n 1 [0] , n 2 ) < 1.5 and n 1 [0] > n 2 (n 1 [0] 2 - n 2 2 ) / (2 n 1 2 ) 0.001 to 0.10
