An examination of the optical properties of index gradients created by Ficks Law diffusion (Preprint)

Abstract

In the last few years, interest in research and development into new ways of creating gradient index optics has increased dramatically. Several new techniques were developed as part of the DARPA-sponsored Manufacturable Gradient Index Optics (M-GRIN) Program. One approach examined in this program was to employ diffusion, governed by Ficks Law, to generate both axial and radial index gradients. However, Ficks Law diffusion tends to yield index gradients that are mathematically uncommon in optical engineering and lens design. The impact of these new gradients on lens aberrations and image quality are not well understood. This paper will examine index gradients that can be described by (makeable by) solving Ficks diffusion laws for both infrared and visible light materials systems.
