Patent ID: 7223024

Claim:
An optical module comprising: a substrate; an optoelectronic device on said substrate; a coupling device on said substrate for optically coupling said optoelectronic device to a guided optical propagation device; said coupling device comprising a reflective surface integrated into said substrate and positioned in an optical path between said optoelectronic device and the guided optical propagation device for permitting mutual optical coupling therebetween, said reflective surface receiving incident optical radiation from the guided optical propagation device and providing reflected optical radiation to said optoelectronic device; a blockage structure in direct contact with the guided optical propagation device for positioning the guided optical propagation device at a preset distance from said reflective surface, said blockage structure comprising at least one support wall coupled to said substrate, and an optical window coupled to said at least one support wall for allowing the optical coupling without interposition of lenses between the guided optical propagation device and said reflective surface, said at least one support wall, said optical window and a surface of said substrate defining a hollow region in which said optoelectronic device is housed.
