Abstract
A novel wafer-scale, compact, in plane solution for interconnecting optical devices with fibers and fiber arrays in a self-aligned “plug-and-play” style is presented. In particular, micro-optical structures on glass wafers, as well as on SiN waveguide grating couplers were designed, optimized, and fabricated. The micro-optical structures are based on re-directing light (reflection) elements, combined with integrated comp like fiber self-alignment structures, fabricated using wafer scale reflow and replication processes. Successful assembly of a 12-fiber ribbon is demonstrated. Excess losses of these structures as low as 0.35 dB are obtained.
