Abstract
An efficient light coupling apparatus for interconnecting two optical components. Light radiation from the first optical component, for example an optical light fiber is directed onto the plane surface of the second optical component, for example a passive waveguide. The light is directed onto the second optical component at a convenient angle such that it impinges on the plane surface of the second optical component at an incident angle. An angularly selective coupling means, for example a volume hologram is located between the first and second optical components for coupling a maximum amount of the light at the incident angle.
