Optical module having lenses aligned on lens-positioning V-groove and fabrication method thereof

An optical module having lenses aligned on a V-groove, comprising:

• a substrate having a top and a bottom surface, said substrate having formed therein first and second optical transferring V-grooves and an optical receiving V-groove, said grooves defining a light transferring path and defining the position for at least one lens disposed in said light transferring path;
• an optical transferring module disposed on the top surface of the substrate and including a laser flip-chip-bonded to the substrate, an optical transferring lens attached at the first optical transferring V-groove for condensing light from the laser, and a laser monitoring optical detector flip-chip-bonded to the substrate and disposed proximate an edge of a side wall of the second optical transferring V-groove and opposite the laser such that an active region of the laser monitoring optical detector is disposed over the second optical transferring V-groove for detecting light from the laser reflecting off the side wall of the second optical transferring V-groove so as to monitor the laser;
• and
• an optical receiving module disposed on the top surface of the substrate and including an optical receiving lens attached at the optical receiving V-groove of the substrate for condensing light externally transferred thereto, and a light receiving optical detector flip-chip-bonded to the substrate and disposed proximate an edge of a side wall of the light receiving V-groove so that an active region of the light receiving optical detector is disposed over the side wall of the light receiving V-groove for detecting the condensed light reflecting off the side wall of the light receiving V-groove from the optical receiving lens.
