Universidad de Zaragoza Ring-type erbium-doped antiresonant reflecting optical waveguide amplifier analysis and design 2018 Access copy available to the general public Unrestricted Erbium-doped antiresonant reflecting optical wave-guides (ARROWs) allow combining wavelength selective guiding due to their attractive spectral versatility with an active operation. In this letter, the analysis and design of a ring-type erbium-doped ARROW amplifier is presented. The influence of the involved passive and active parameters (ring thickness and diameter, refractive index variation, pump and signal wavelengths, Er3+-ion concentration, and input pump power) on the spectral response of the structure and the optical power propagation losses and on the amplifier performance is numerically analysed. The opposite influence of the ring diameter on the optical power confinement and on the pump power density causes the existence of a diameter value that maximizes the amplifier net gain. For a cladding refractive index of 1.4 and moderate index variations, ¿ n = 0.2-0.4, the optimum ring diameter is in the range of 20 µm. To compensate signal confinement losses (a few dB/cm), high erbium concentrations (~ × 1026 ion/m3) are required. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/ES/MINECO/TEC2014-52642-C2-2 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.553 2018 ENGINEERING, ELECTRICAL & ELECTRONIC 119 / 265 = 0.449 2018 Q2 T2 PHYSICS, APPLIED 54 / 148 = 0.365 2018 Q2 T2 OPTICS 38 / 95 = 0.4 2018 Q2 T2 0.991 2018 Atomic and Molecular Physics, and Optics 2018 Q1 Electronic, Optical and Magnetic Materials 2018 Q1 Electrical and Electronic Engineering 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-8431-0003 Vallès, J.A.
