Geometrical optics analysis of multi-layer GRIN tapers
Abstract
Several gradient-index (GRIN) tapers have been analyzed in the literature, whether with a transverse parabolic index distribution or with a hyperbolic secant index profile. In this work, a new class of GRIN tapers, formed by grouping together several sections of transverse parabolic index devices is analyzed, focusing the attention on some of its limitations and advantages over ordinary tapers. Numerical simulations based upon geometric optics are conducted to analyze the behavior of these tapers.
