Abstract
Disclosed is a facet coupling fanout device including a body, a first optical coupling side, and a second optical coupling side. The body defines a plurality of multi-channel waveguides therein. The first optical coupling side optically couples the plurality of multi-channel waveguides to a plurality of waveguide cores of a photonic integrated circuit (PIC). The a second optical coupling side optically couples the plurality of multi-channel waveguides to optical fibers of a fiber array unit (FAU). The first optical coupling side defines a first pitch Pbetween the plurality of multi-channel waveguides and the second optical coupling side defines a second pitch Pbetween the plurality of multi-channel waveguides where P>P. The first pitch Pand the second pitch Pdefine a pitch ratio
