Presentation title:

Ring-Core Optical Fibers for OAM Modes

Abstract: 

Spatial division multiplexing (SDM) has been demonstrating great potential to tremendously increase the data capacity and spectral efficiency in optical communication systems. Recently, optical fiber communications using SDM technology carried by orbital angular momentum (OAM) modes has gained much attention.

In this talk, we will introduce the basics of optical OAM and discuss the latest progress on ring-core optical fiber supporting OAM modes for various applications. First, newly designed air-core ring fiber for supporting 1322 vortex modes and multi-ring air-core fiber supporting a total of 2280 vortex modes at 1550 nm will be introduced. Next, we will discuss two-octave SC generation of up to OAM_17,1 mode spanning from 1560 to 6250 nm in the ring-core fiber. Furthermore, a highly dispersive coupled ring-core fiber (CRF) with two concentric high-index rings for OAM modes will be presented. These ring-core fiber designs have further enriched the building blocks for fiber-based OAM systems.
