Patent ID: 6912332

Claim:
A parallel optical interconnection module, comprising: a substrate having a heat spreader thereon and in which an electrode pad and given electronic circuit patterns are formed; a silicon optical bench formed on the substrate and having a trench; a light source/photodetector formed within the trench of the silicon optical bench and having a light source and a photodetector, wherein said light source generates an optical signal to output the signal toward the outside through an aperture and said photodetector receives the optical signal incident through the aperture from the outside and then converts the optical signal into an electrical signal; a driving unit/receiving unit formed on the substrate and having a driver and a receiver, wherein said drive drives the light source depending on the electrical signal supplied through the electrode pad and said receiver amplifies the electrical signal from the photodetector to output the amplified signal to the electrode pad; an optical waveguide having a core formed between lower and upper clad layers and having a reflection surface formed at the end of the core; an adaptor connected to a connector connected to an optical fiber; and a ferrule for fixing the optical waveguide to the adaptor, wherein said substrate and said adaptor are coupled so that the aperture and the reflection surface are opposite.
