“…This has renewed the interest in gradient refractive index (GRIN) materials, which are a natural choice for compact optical design . GRIN rod lens is a cylindrical medium with a parabolic refractive distribution in which the refractive index is highest on the rod's optical axis and decreases toward the periphery with the square of the radial distance from the optical axis and has been used widely in image‐transmission systems and optical communication systems such as copy machines, facsimile lens arrays, and optical circuit networks. Glasses and polymers are the two well‐known materials applied in the optical field.…”

We present an approach to an analysis of the chromatic aberrations of gradient refractive index polymeric rod lens. Two kinds of materials system are used in this study: diallyl phthalate‐methyl methacrylate and diethylene glycol bis(allyl carbonate)‐poly (1,1,5‐trihydroperfluoropentyl methacrylate). The results of a numerical simulation reveal that the chromatic aberration of the focal length, the longitudinal, and lateral chromatic aberrations depend on the ratios between the change in periodic length caused by wavelength and the periodic length. By reducing the ratios, the chromatic aberration of focal length, the longitudinal and lateral chromatic aberrations at any lens length are decreased effectively. © 2013 Wiley Periodicals, Inc. J.

Large elliptical nanostructured gradient-index microlens

et al. 2015

We demonstrate the feasibility of the development of a gradient-index elliptical microlens with a size of 75×125 μm using nanostructured glass technology. The gradient index is obtained by means of a discrete internal structure composed of two glasses with feature sizes much smaller than the wavelength of the incident light. A modified photonic crystal fiber-drawing technique is used for the lens fabrication. The elliptical shape of the lens is obtained by a novel final drawing stage where the spherically symmetric lens preform is drawn into an elliptical form by collapsing two large air holes placed in the preform during assembly. The effective focal lengths of 160 and 260 μm for the orthogonal axes are obtained experimentally for the fabricated lens, and show good agreement with those predicted by the effective medium theory and the full-wave beam propagation simulations.
