OPTICAL MODULE AND ASSEMBLING METHOD THEREFOR

摘要

An optical module capable of collectively specifying angles of a plurality of optical fibers with respect to a flat−plate micro−lens array when a plurality of micro−lens optical axes are collectively aligned with a plurality of optical fibers for passively fixing, the module comprising a flat−plate micro−lens array having a plurality of circular micro−lenses arranged on one surface of a flat−surface transparent substrate, a fitting transparent substrate having a plurality of fine fitting recesses arranged in one surface of a flat−surface transparent substrate, a first optical fiber guide substrate having a plurality of fine guide holes arranged in and penetrating a flat−surface substrate, a second optical fiber guide substrate having a plurality of fine guide holes arranged in and penetrating a flat−surface substrate, and a plurality of optical fibers having the tip−end core portions thereof exposed convexly to serve as fine fitting convex portions.
