Abstract
Passive alignment and connection between a fiber array and a plurality of optical waveguides terminating along an edge of a photonic IC (PIC) is provided by a controlled mating between alignment V-grooves formed in a fiber array support substrate and extra-array alignment ridges formed beyond the extent of a waveguide array integrated within the PIC. The height and width of the alignment ridges are formed to engage with the alignment V-grooves upon mating of the fiber array substrate with the PIC, providing passive alignment while maintaining a physical gap spacing g between the components (ensuring the integrity of the passive alignment).
