Session 7: Photonics for Datacenter and Metro Networks (Feb-6 2020, 1:50pm - 4:20pm)

Abstract: Short-reach transmission technologies based on multimode sources and fiber infrastructure remain highly attractive and competitive against single-mode solutions. We present here details of a versatile integrated multimode simulation framework targeting the design, analysis, and optimization of such systems. Important aspects that are addressed here are detailed multimode signal representations, mode solvers, models for signal propagation in multimode fibers, multimode VCSEL models, models to calculate the coupling between
various multimode devices, and system-level building blocks specifying and measuring the characteristics of the overall system. Besides discussing device modeling details, we present virtual test benches for measuring typical characteristics, such as the Encircled Flux of the launch system, DMD and EMBc of the multimode fibers, as well as system performance characteristics, to determine whether the simulated system and its individual components meet industry-accepted requirements.
Session 10: Optical Interconnect Devices II (Feb-6 2020, 11:00am - 12:20pm)

Abstract: Capacity demand for network connections within and between datacenters is increasing relentlessly, fueling the need for deployment of new and improved optical communications equipment. Confronted with the task of developing innovative solutions to address this challenge, engineers must deal with and consolidate countless design choices that are influenced by a large variety of constraints. We present design examples at the system- and component-levels, illustrating the challenges in modeling, analyzing and optimizing technology choices and equipment parameters of optical interconnects for intra- and inter-datacenter applications.
We demonstrate a seamless design flow linking simulations of the electronic circuits at the transmitter/receiver with simulations of the optical fiber link, enabling investigation and optimization of the overall system performance. Further, we compare advantages and challenges of multimode infrastructure solutions utilizing, for instance, PAM-4 modulation of multi-mode VCSELs with transmission over wide-bandwidth multi-mode fibers, and single-mode solutions employing Mach-Zehnder modulators with tunable DFB lasers in WDM operation over SMF-links.
