Universidad de Zaragoza (orcid)0000-0001-8431-0003 Requirements for gain/oscillation in Yb3+/Er3+-codoped microring resonators 2015 Access copy available to the general public Unrestricted A detailed model of the performance of a highly Yb3+/Er3+-codoped phosphate glass add-drop filter, which combines the propagation at resonance of both pump and signal powers inside the microring resonator with their interaction with the dopant ions, is used to analyze the requirements for gain/oscillation in these structures. Special attention is paid to the influence of additional coupling losses and asymmetry between the input/output couplers. It is concluded that, due to small signal gain saturation and the limited range of pump amplitude coupling coefficients, asymmetry does not greatly influence gain/oscillation requirements through the pump intensity build-up inside the ring. Asymmetry effect on small signal intensity transfer rate and threshold gain instead allows a significant lightening of the demanding doping ions concentrations requirements to achieve oscillation. info:eu-repo/grantAgreement/ES/DGA/POSDRU-89-1.5-S-52603 info:eu-repo/grantAgreement/ES/MINECO/TEC2013-46643-C2-2-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.24 2015 Applied Mathematics 2015 Computer Science Applications 2015 Electronic, Optical and Magnetic Materials 2015 Electrical and Electronic Engineering 2015 Condensed Matter Physics 2015 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion Galatus, R. 2002 647 Universidad de Zaragoza Dpto.
