However, the response of these photonic structures highly depends on the grating parameters and working conditions, so modeling their behavior and dependences becomes fundamental. In this work, a numerical method has been implemented to simulate the optical power propagation along an Er/Yb-codoped integrated waveguide Bragg grating as a function of its most relevant operational parameters. The results obtained show the optimal conditions to maximize its performance as a highly amplifying reflector, but also its capability as a monolithic laser. In addition, the modeling results adequately match experimental values measured in fs-laser written structures in Er/Yb-codoped phosphate glass, supporting the accuracy of the numerical method developed and its usefulness for further optimizing these promising photonic structures. info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-20R info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-108598GB-I00/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MICINN/PID2020-112770RB-C21 info:eu-repo/semantics/embargoedAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.1 2023 MATERIALS SCIENCE, CERAMICS 3 / 31 = 0.097 2023 Q1 T1 0.938 2023 Electronic, Optical and Magnetic Materials 2023 Q1 Ceramics and Composites 2023 Q1 Surfaces, Coatings and Films 2023 Q1 Materials Chemistry 2023 Q1 Process Chemistry and Technology 2023 Q2 9.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Ariza, Rocío Benedicto, David Universidad de Zaragoza (orcid)0000-0002-3867-2182 Macias-Montero, Manuel Vallés, Juan A.
