PASSIVE FIBER ALIGNMENT ARRANGEMENT FOR COUPLING TO NANO-TAPER OPTICAL WAVEGUIDES

摘要

An arrangement for providing passive alignment between an optical fiber 30 and the "tip" of a nanotaper 50-T coupling waveguide (the nanotaper formed within the SOl layer of an SO-based optoelectronic arrangement). The arrangement includes a separate fiber carrier support element 10, including a longitudinal V-groove 14 for supporting the fiber 30 and an alignment feature 16 formed parallel thereto. The SOl structure 40 is formed to include an associated alignment slot 48, so that as the fiber carrier 10 is positioned over and attached to the SOI structure 40, the alignment feature 16 and alignment slot 48 will mate together and provide passive alignment of the optical fiber 30 to the nanotaper waveguide tip 50-T.
