Optical module and assembling method thereof

A method for assembling an optical module comprising the steps of:

• preparing a planar microlens array having a plurality of microlenses formed in at least one surface thereof;
• adhering one surface of the planar microlens array to one surface of a planar fitting transparent substrate, the planar fitting transparent substrate having a plurality of micro fitting recesses formed in the other surface thereof, in such a manner that the center of each recess is aligned to the center of each microlens,
• stacking and adhering a plurality of guide substrates for optical fibers to each other, each of the guide substrates having a plurality of micro guide holes opened therethrough with each guide hole being aligned to the center of a corresponding recess;
• and
• adhering the stacked guide substrates to the other surface of the fitting transparent substrate.
