ABSTRACT:
In a method for coupling an optical waveguide to a light emitting diode (LED) within a resin case, an input end of the optical waveguide is mounted proximal to a surface formed in the resin case parallel to a light-emitting face of the LED. The optical waveguide and the resin case can be bonded by a light or thermally curable resin that is applied and subsequently solidified. The light or thermally curable resin may be a photopolymer sensitive to light emerging from the waveguide. An automated coupling system is provided to optimize the coupling conditions using the in-coupled light efficiency feedback and controller. Finally a method is described allowing the coupling efficiency to be controlled using external excitation forces or light intensity variations, using electro-optic, magneto-optic, thermo-optic, light polarization sensitive or nonlinear properties of the filler material used between the resin case and waveguide.
