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