This paper presents the results of numerical simulations of a ring-core thulium-doped silica fiber (RC-TDF). Enhanced spontaneous emission (ASE) was generated for a fiber with 4wt.% thulium content. An analysis of the formation of the ASE spectrum parameters (λmax, FWHM, output power) as a function of fiber length is also shown. The modal map is presented as a combination of outer and inner core radii and ∆n.
