Abstract

Optical interconnect is a novel integration approach that combines optics and silicon between CPUs to meet the requirements of next generation AI computing and data center transmission systems. In these applications, the attachment with precision alignment of multiple fibers from 12 to 16 with their corresponding waveguides is crucial and challenging to establish efficient optical interfaces. We employ a passive alignment technique, utilizing a V-groove structure to accommodate 16 single-mode fibers directly coupling to waveguides without additional optical components. This paper presents results of optical coupling with low losses and variations across all fiber-waveguide pairs.
