The polymer graded index (GRIN) lens with high impact resistance can be made by easy technique, but the thermal stability is not so excellent. In this study, we propose a new method of fabricating organic–inorganic microcomposite cylindrical GRIN lens. This method is based on spontaneous frontal polymerization technique and diffusion of two organic materials with different refractive indices to an inorganic wet-gel. The obtained microcomposite cylindrical GRIN lenses are not only thermally stable, but also have a controlled refractive index profile due to its inorganic matrix.
