Abstract:
A multifunctional intelligent optical module platform, capable of constructing optical channel monitor, comprises:a substrate with planar lightwave circuit fabricated thereto; light-transmitting waveguides of said planar lightwave comprising first and second waveguides, wherein said first waveguide is an optical pass-through waveguide interfaced with light-transmitting optical fibers, and said second waveguide is a single or a plurality of optical signal-tap waveguide in order to couple out a portion of optical signals from said optical pass-through waveguide; a signal branching waveguide structure, wherein said optical pass-through waveguide and said optical signal-tap waveguide interface with each other through said signal branching waveguide structure; a single or a plurality of trench with substantially vertical sidewalls terminating said optical signal-tap waveguide; a single or a plurality of micro mirror with a small footprint size being inserted into said trench in order to couple out optical signals from cores of said optical signal-tap waveguide in a direction substantially normal to major surfaces of said planar lightwave circuit; and a single or a plurality of electronic chip, photonic chip, or any combination thereof being interfaced to said planar lightwave circuit in order to provide electrical-to-optical signal conversion, optical-to-electrical signal conversion, information processing, feed-back control, signal driver, external data communication, or any combinations thereof.
