| 摘要 |
<p>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.</p> |
