Abstract
We developed and analyzed a novel multiring construction of a silica glass, large mode area, double-clad optical fiber co-doped with Tm3+/Ho3+.The proposed fiber preform was fabricated using Modified Chemical Vapor Deposition Chelate Doping Technology. The proposed novel approach allowed for selective doping of core layers with Tm3+and Tm3+/Ho3+ions. This technological advancement offers precise control over doping profiles, which is essential for optimizing the amplified emission spectra (ASE). The optical fiber construction is characterized by 20/250 mu m dimensions (core/cladding), mode field diameter of LP01 = 20.74 mu m a low numerical aperture (NA = 0.118), and Gaussian output beam (R2 = 0.99). The maximum weight concentrations of Tm2O3 and Ho2O3 were measured at 0.47 % and 0.18 %, respectively. ASE spanning from 1.35 mu m to 2.2 mu m across different fiber lengths are presented. This ASE spectrum results from the superposition of emission bands at 1.45 mu m (Tm3+: 3H4 -> 3F4), 1.8 mu m (Tm3+: 3F4 -> 3H6), and 2 mu m (Ho3+: 5I7 -> 5I8). The emission spectra full width at half maximum (FWHM-3 dB) decreases from 270 nm to 207 nm as the fiber length varies from 2 to 21 m. This fiber design, characterized by excellent mode quality and broadband emission, offers potential for advanced ASE sources.
