Abstract
The present disclosure relates to a fiber optic assembly including a flexible substrate and a plurality of optical fibers having affixed segments bonded to the flexible substrate along fiber routing paths. The optical fibers having first ends positioned at route termination locations corresponding to optical connection locations. The fiber optic assembly also includes a planar lightguide circuit chip having lightguides optically connected to second ends of the optical fibers including a silicon substrate and a core layer supported by the silicon substrate. Optical signal paths are defined that extend continuously from the first ends of the optical fibers through the second ends of the optical fibers to the lightguides without any optical fiber splices being located along the optical signal paths. The optical device also includes a spring mounted to the planar lightguide circuit chip for biasing the optical fiber into the alignment groove.
