Patent ID: 7167618

Claim:
An optical module comprising: a planar microlens array having a plurality of microlenses formed in at least one surface thereof; a planar fitting transparent substrate, one surface thereof being adhered to one surface of the planar microlens array, and a plurality of micro fitting recesses being formed in the other surface thereof with the center of each recess being substantially aligned to the center of each microlens; and a plurality of guide substrates for optical fibers stacked and adhered to each other along opposing surfaces of the guide substrates, the stacked guide substrates being adhered to the other surface of the fitting transparent substrate, each of the guide substrates having a plurality of tapered micro guide holes opened therethrough with opposing guide holes being substantially aligned to each other, and each guide hole being substantially aligned to a corresponding recess, wherein the stacked guide substrates are configured to be in contact with each optical fiber along respective multiple displaced annular rings formed by the opposing guide holes.
