Speech title: Optical Communications System and Networking Using Multiplexed Orbital Angular Momentum Modes

Abstract: Optical communications, as the backbone of today's telecommunications infrastructure, supports voice, video and data transmission through global networks. One critical issue in its research is the challenge of meeting the needs of increasing the data capacity. This tutorial presents high-speed fiber and free-space optical communications and networking using orbital-angular-momentum multiplexing.

First, the basics of orbital angular momentum (OAM) and its traditional applications will be introduced. As another newly explored dimension, spatial division multiplexing (SDM) has been demonstrated with the great potential to tremendously increase the data capacity. The building blocks of OAM-based SDM system will be discussed. Next, we will discuss the potential of using orbital-angular-momentum (OAM) modes for spatial multiplexing in a ring fiber. Several types of ring-core optical fibers for OAM modes will be presented, including multi-core ring fiber supporting thousands of OAM modes, coupled ring-core fiber with large negative dispersion, non-zero dispersion-shifted ring fiber to balance the chromatic dispersion and nonlinearity. Moreover, we will show mode-division and wavelength-division multiplexing of OAM modes with 1.6-Tb/s data capacity through 1.1-km of ring-core fiber. Finally, we will review wavefront-phase-tailoring methods to reconfigurably manipulate and perform different networking functions on multiplexed OAM beams. Specifically, the optical functions of add/drop multiplexing, selective switching and multicasting are reported for OAM beams.
