b Equivalent geodesic double-layer lens, where the refractive index is placed with an out of plane deformation z(ρ) of the upper/lower waveguide described by the arc length s1,2(ρ) of the surface measured along the meridian from the axis of symmetry under a cylindrical coordinate system (...
In the case when two glass structures having different refractive index distributions in their end surfaces are joined, they may be joined through a suitable lens system. Moreover, in the latter case, that is, when two light-conducting glass structures having focusing effect and different ...
A novel three-dimensional (3D) optical lens structure for electromagnetic field shaping based on spatial light transformation method is proposed at microwave frequencies. The lens is capable of transforming cylindrical wavefronts into planar ones, and ge
Instead of a ball lens, a gradient index lens is frequently used as a fiber coupling device. Such a lens has a gradient profile in which the refractive index varies in the direction perpendicular to the optical axis, as expressed in Eq. (5.23). where N0 is the base index (at the cente...
