28 January 2017 Cost-effective light-emission optical sub-assembly for datacenter networks
Author Affiliations +
Technologies for creating cost-effective light-emission optical sub-assemblies (OSAs) are discussed from the point of view of laser diodes. A lens-integrated surface-emitting laser (LISEL), consisting of a DFB laser, integrated mirror, and integrated convex lens, has the potential to achieve light-emission OSAs. An OSA based on the LISEL is proposed, and the capabilities of direct and passively aligned optical coupling, isolator-free operation, non-hermetic packaging, and on-wafer testing are introduced.
