Optical waveguide devices and methods of fabricating the same

An optical device comprising:

• a waveguide holding member comprising a first transverse surface region and an optical waveguide;
• a lenslet array holding member comprising a second transverse surface region which confronts the first transverse surface region of the first waveguide holding member and a lenslet array;
• and
• an alignment mechanism which aligns an end of the optical waveguide relative to the lenslet array and which is formed at the first and second transverse surface regions of the respective waveguide holding member and the lenslet array holding member, wherein the lenslet array is on the second transverse surface region of the lenslet array holding member and the first transverse surface region is planar in the region opposite the entire lenslet array.

• and
• an alignment mechanism which aligns an end of the optical waveguide relative to the lenslet array and which is formed at the first and second transverse surface regions of the respective waveguide holding member and the lenslet array holding member, the alignment mechanism comprising a plurality of pits formed in the first transverse surface region of the waveguide holding member and a plurality of protrusions extending from the second transverse surface region of the lenslet array holding member and into the plurality of pits, respectively,
• wherein the lenslet array is separate from the alignment mechanism.
