Abstract
An improved optical module having lenses aligned on a lens-positioning V-groove and a fabrication method thereof which includes a silicon substrate, which defines a light transfer path below a surface thereof, including light transferring V-grooves and a light receiving V-groove, and lens-positioning V-groove for determining the position of a lens, wherein two lens-positioning V-grooves are formed therein, an optical transmitter module including a laser which is a light source and is flip-chip-bonded to the substrate by a solder bump after an optical waveguide is previously aligned with the V-groove by using an alignment mark behind the vertical portion of the light transferring v-groove. A light transferring lens attached on one lens-positioning V-groove for condensing the light from the laser, and a laser monitoring optical detector arranged on a side wall opposite the laser of the light transferring V-groove, wherein an active region is flip-chip-bonded toward the substrate, for monitoring the laser, and an optical receiver module including a light receiving lens attached on the lens-positioning V-groove of the silicon substrate for condensing beam externally transferred thereto…
