Multi-element fiber for space-division multiplexed optical communication system [PDF]

, 2014
This paper reviews a novel approach of implementing space-division multiplexing (SDM) based on Multi-element Fiber (MEF) technology. The MEF geometry provides for ultra-low crosstalk between the spatial channels while full compatibility with standard WDM

A Unified Approach to Achieving High Power and High Energy in Chirally Coupled-Core Ytterbium-Doped Fiber Amplifier Systems

IEEE Photonics Journal, 2018
An approach based on a comprehensive, unified model for fiber laser and amplifier systems is used in the design of high-power, high-energy systems. With guidance from the model, a chirally coupled-core Yb-doped fiber amplifier system is constructed.

High power, single-frequency, monolithic fiber amplifier for the next generation of gravitational wave detectors.

Optics Express, 2019
Low noise, high power single-frequency lasers and amplifiers are key components of interferometric gravitational wave detectors. One way to increase the detector sensitivity is to increase the power injected into the interferometers. We developed a fiber
