Abstract:
An optical power divider including:an input port; first, second, third and fourth output ports; a single branching area; an input optical waveguide coupling said input port to said branching area; first, second, third and fourth output optical waveguides coupling said branching area to said first, second, third and fourth output ports, respectively; a beam separator, centrally disposed within said branching area, for evenly separating light, input via said input port and said input optical waveguide, around a branch point and towards said second and third output optical waveguides; and first and second beam expanders disposed along opposite outer sides of said branch area for expanding the light, separated by said beam separator, outward to prevent the separated light from gathering around the second and third output ports, the separated and expanded light being uniformly output through said first, second, third and fourth output ports via said first, second, third and fourth output optical waveguides.
