Abstract

We measure the reflectivity of the textured GaAs surface to confirm if it possesses the optical properties of a graded index layer. Using the cross section micrographs of the textured sample, we measured its texture thickness and use it as the length of the graded index region. Experimental reflectivity measurements exhibit a good match to that of the numerical simulations for a graded index thin film.
