Electric Field-Induced Mode Switching in Few-Mode Fibers

Abstract

In the past few years, there has been a lot of R&D attention in developing optical fiber based technologies in photonics and broadband communication system. Data communication, cloud computing has demanded an exponential growth in communication traffic. To overcome it, few-mode fibers and mode division multiplexing (MDM) has emerged as a favorable solution. Mode convertors play a crucial role as key components in MDM systems. Numerous types of mode convertors have been proposed and experimentally demonstrated so far, employing diverse techniques such as acoustooptic transducers, structured optical waveguides etc. [1].
