Patent ID: 7684667

Claim:
A hybrid integrated structure, comprising: an output optical fiber array, comprising: a substrate; a plurality of V-shaped trenches formed in the substrate; one or more optical fibers and one or more reflection mirrors that are alternately arranged, inserted, and disposed in the plurality of V-shaped trenches; the structure further comprising: a Planar Lightwave Circuit (PLC) device using an optical fiber array, the PLC comprising: one or more planar optical waveguides; an upper cladding layer; one or more photodiodes integrated on the upper cladding layer above the one or more planar optical waveguides; the structure further comprising: a section located on a boundary surface between: a) output optical waveguides which is at an end of the PLC device in a direction of propagation of light, and b) an input end of an output optical fiber array, the section being ground at a predetermined inclined angle with respect to an optical axis.
