Optical interfacing device with an array of tapered optical fibers

A method, comprising:

• constructing an optical interfacing device, wherein the constructing comprises:
• securing first subsections of total lengths of optical fibers into a volume of a support structure, wherein second subsections of the total lengths of the optical fibers remain exposed outside of the volume of the support structure;
• and
• tapering the second subsections of the total lengths of the optical fibers such that the second subsections comprise tapered ends;
• and
• coupling the optical interfacing device to a photonic wafer such that adiabatic coupling is enabled between the tapered ends of the optical fibers and optical elements of the photonic wafer.

An optical interfacing device, comprising:

• optical fibers with tapered ends, wherein the tapered ends enable adiabatic coupling;
• a support structure, wherein:
• first subsections of total lengths of the optical fibers are secured into a volume of the support structure;
• and
• second subsections of the total lengths of the optical fibers, comprising the tapered ends, remain exposed outside of the volume of the support structure;
• and
• a dielectric material that has been deposited onto exposed surfaces of the optical fibers and the support structure.
