Concentric layers with heterogeneous doping for cladding-pumped L-band fiber amplifiers

Abstract

In this paper, we demonstrate that a carefully engineered combination of erbium doped layers and erbium-ytterbium codoped layers in a single core (concentric layers with heterogeneous doping) can improve the power conversion efficiency (PCE) compared to homogeneous doping designs. We compare the PCE and noise figure (NF) of four types of homogeneous doping geometries in the core (annular Er, annular Er/Yb, central Er and central Er/Yb) with a design based on concentric layers with heterogeneous doping. For all the scenarios, the doping geometry and fiber length are carefully optimized to maximize the PCE.

Charles Matte-Breton was born in Québec City, Canada, in 1994. He is currently pursuing a Ph.D. degree in Electrical Engineering at the Centre for Optics, Photonics, and Lasers (COPL), Université Laval, QC, Canada. His research interests include doped fiber design, fiber components and communication networks. Recipient of the prestigious Alexander-Graham-Bell Ph.D. scholarship, Charles also completed a six-month internship at Nokia Bell Labs, in 2018. His main contribution to research so far has been his role in the development of a novel fuseless optical fiber side-coupling method based on a half-taper which he presented at OFC 2020 where it garnered considerable interest from the optical communication community.
