摘要：A method and circuit is provided for more efficiently coupling light between twooptical waveguides such as optical fibres (12a,12b). When the two waveguides are coupledto spaced apart collimating lenses such as GRIN lenses (10a,10b), the beam propagatingbetween the spaced part lenses may be shifted. In this instance light can more efficientlybe coupled out of the output optical fibre (12b) if it is angled with respect to the opticalaxis of the GRIN lens (10b) to which it is coupled. This invention provides an output fibrethat is non-parallel with the optical axis of the lens it is coupled thereto. An application ofthe device using a thick optical filter (12) between the two GRIN lenses (10a,10b) isdescribed.
