Abstract
An optical module is provided in which the angles of the optical fibers to be inclined with respect to the planar microlens array may be regulated at the same time when respective optical axes of the microlenses and respective optical fibers are passively aligned. The optical module of the present invention comprises a planar microlens array having a plurality of microlenses formed in one surface thereof, a planar fitting transparent substrate having a plurality of micro fitting recesses formed in one surface thereof, a planar first guide plate having a plurality of micro guide holes opened therethrough, a planar second guide plate having a plurality of micro guide holes opened therethrough, and a plurality of optical fibers each end thereof having a micro fitting convex portion.
