Solution deposited optical waveguide lens

Solution deposited optical waveguide lens
Solution deposited optical waveguide lens
The development of a solution deposited optical waveguide lens, whose focusing effect is produced by an effective index gradient with a hyperbolic secant variation, is described. The lenses are fabricated by a microcontrolled dip coating procedure from colloidal SiO2:TiO2 solutions. Both the design and construction of the lens, along with the analytical and experimental results of the focusing properties, are described. The best lenses had speeds of ∼f/10 and focal spots ∼1.2 times the diffraction limit at apertures of 2.0 mm.

Abstract

The development of a solution deposited optical waveguide lens, whose focusing effect is produced by an effective index gradient with a hyperbolic secant variation, is described. The lenses are fabricated by a microcontrolled dip coating procedure from colloidal SiO2:TiO2 solutions. Both the design and construction of the lens, along with the analytical and experimental results of the focusing properties, are described. The best lenses had speeds of ∼f/10 and focal spots ∼1.2 times the diffraction limit at apertures of 2.0 mm.
