摘要： An optical waveguide splitter with a symmetric splitting power ratio having one input port and two output ports, includes a substrate and one or more vertical waveguide layers deposited thereon or diffused thereinto, and optionally one or more cladding layers deposited upon the waveguide layer(s). The waveguide layers and optionally one or more cladding layer together and optionally with the substrate form a profile of the refractive index that supports the propagation of light in a plane substantially parallel to the substrate. On both sides of the input port, the waveguide sidewalls terminate at a depth deeper than the location of the peak intensity of the beam transporting propagating light energy within the input port, and the sidewalls on both sides of each output port terminate at a depth shallower than the location of the peak intensity of the beam transporting the majority light energy within each output port.
