WebOct 1, 2007 · It has been determined that the Klopfenstein taper [Proc. IRE 44, 31 (1956)] produces the optimum graded-index profile with the smallest depth for any specified minimum reflectance. WebA waveguide in which the index profile has abrupt changes between the core and the cladding is called a step-index waveguide, while one in which the index profile varies gradually is called a graded-index waveguide. We will focus on the step-index waveguide for our discussion. n 1 n 2 n 3 x y z n(x) n(x) n 2 n 3 x y z n(x)
