Hybrid lens beam waveguide

An optical beam waveguide consisting of a central aperture and a surrounding lens-a hybrid lens guide-possesses some important advantages of both iris guides and lens guides. Compared to an iris guide, it has a lower loss, and for small curvatures, is less sensitive to bends. Also it is less subject...

Description
Summary:An optical beam waveguide consisting of a central aperture and a surrounding lens-a hybrid lens guide-possesses some important advantages of both iris guides and lens guides. Compared to an iris guide, it has a lower loss, and for small curvatures, is less sensitive to bends. Also it is less subject to breakdown than a lens guide. A theoretical study is presented. The hybrid lens guide can be specified by four parameters; the loss is investigated as such effects are also discussed.
