Abstract:
An optical coupling device for coupling light emitted by an array of laser diodes into at least one waveguide, the device comprising:a substrate; a plurality of waveguide sections of said at least one optical waveguide affixed to the substrate in a parallel relationship with each other, each of said waveguide sections having a light: propagating layer extending along a longitudinal axis and a groove extending therein transversally to said longitudinal axis, said groove reaching into the light propagating layer; and a coupling element for coupling light from a plurality of laser diodes of said array into said waveguide sections, the coupling element having a first end optically coupled to the plurality of laser diodes for receiving the light therefrom, and a second end extending in the groove of each of said plurality of waveguide sections and having at least one reflection interface oriented to reflect said light to propagate into the light propagating layer of the corresponding waveguide section.
