Abstract
An optical light coupling system is provided which includes an optical waveguide having a slanted end face, a lens for receiving a beam of light from the optical waveguide, wherein an optical axis of the lens defines a line extending through a center of the light guiding portion of the optical waveguide, and a powerless non-birefringent element disposed between the optical waveguide and the lens along the line defined between the optical axis of the lens and the center of the optical waveguide for maintaining a substantially linear propagation of the beam of light along the line, wherein the powerless non-birefringent element has a first end face facing an end face of said optical waveguide and defining an angle therebetween, and a second end face facing the lens. This angle can be adjusted to accommodate imperfect refractive index matches.
