ABSTRACT:
An optical coupling system comprises a radiation emitting device and a radiation receiver. The radiation emitting device has an emitting end face and emits radiation having an optical axis of symmetry which is inclined at an output angle relative to the direction perpendicular to the emitting end face. The radiation receiver has a receiving axis and a receiving end face which is inclined at a wedge angle relative to a plane perpendicular to the receiving axis and the receiving end face is positioned adjacent the emitting device. The receiving end face may be first inclined at the wedge angle such that the optical axis of incident radiation is inclined at an angle relative to the normal of the receiving end face. The receiver is then positioned such that the receiving axis is inclined at a receiving angle relative to the normal of the receiving end face such that the radiation propagates about in the direction of the receiving axis.
