Biomimetic Gradient Index (GRIN) Lenses
A new class of hierarchically structured polymer optical materials possessing an internal refractive index gradient that mimics biological optical materials is described. The new materials permit the fabrication of gradient refractive index (GRIN) lenses with an unprecedented variety of index gradients. Gradients with different functional forms in both the radial and axial directions have been ...
متن کاملPorous Silicon Gradient Refractive Index Micro-Optics.
The emergence and growth of transformation optics over the past decade has revitalized interest in how a gradient refractive index (GRIN) can be used to control light propagation. Two-dimensional demonstrations with lithographically defined silicon (Si) have displayed the power of GRIN optics and also represent a promising opportunity for integrating compact optical elements within Si photonic ...
متن کاملThomas Young's investigations in gradient-index optics.
PURPOSE James Clerk Maxwell is usually recognized as being the first, in 1854, to consider using inhomogeneous media in optical systems. However, some 50 years earlier, Thomas Young, stimulated by his interest in the optics of the eye and accommodation, had already modeled some applications of gradient-index optics. These applications included using an axial gradient to provide spherical aberra...
متن کاملPrimary aberration coefficients for axial gradient-index lenses
As for homogeneous lenses, for axial gradients the analysis of the Seidel and chromatic aberration coefficients can be very useful in lens design. However, at present few commercial optical design programs list the Seidel aberrations of GRIN lenses and none of them lists the chromatic aberrations. In order to facilitate the computer implementation of the chromatic aberrations of axial GRIN lens...
متن کاملBirefringent properties of diametrically loaded gradient-index lenses.
Gradient-index (GRIN) lenses have been widely used as collimators in various fiber-optic sensors and as optical coupling devices in components designed for optical communication systems. However, relatively little attention has been paid to the birefringent properties of GRIN lenses and the potential for using them as photoelastic sensing elements in optical transducers. Analytical and experime...
