“…The emission spectrum approaches 58 nm of bandwidth value, which is broad compared to silica fiber for examples (emission bandwidth of 35 nm as reported in [28]). This broad emission is a result of inhomogeneous broadening originating from local site-to-site variation in emitting centers' surrounding field in the lattice environment as suggested in [29].…”

International audienceWe demonstrate super-broad luminescence over 70 nm of bandwidth and spectral hole-burning effect obtained in just a few cm of novel air-clad, highly concentrated Er/Yb-doped phosphate fiber. The fiber is drawn from preforms of glasses within the P2O5 - SrO - Na2O composition. The fabrication process, thermal, structural, and optical properties of the fiber are described.

“…Brown and Hoffman [11] developed a conventional temperature distribution model for continuous-wave (CW) fiber lasers. Using this model, the temperature distribution inside the active fiber can be described by the heat-conduction equation [12]. Combined with the continuous boundary conditions [13,14] of a fiber, the following analytical expressions for the radial temperature distribution T(r) in the core, cladding and coating regions can be formulated [14] where a, b, and c denote the radii of the core, inner cladding, and coating, respectively; k 1 , k 2 , and k 3 represent the heat conductivities of the core, inner cladding, and coating region, respectively; T 0 is the center temperature of the core; T C is the coolant temperature; Q(z) is the heat power density along the fiber [15], which can be expressed as follows…”

A numerical model is established to predict the beam quality factor M2 of fiber laser for the first time. The finite-difference beam propagation method (FD-BPM) is introduced to simulate the beam propagation of thulium-doped fiber lasers (TDFLs) with given design parameters. The output beam profile can be calculated for an active fiber with complex refractive index profiles and various bending radii. The beam quality factor M2 can be obtained by the calculated beam profile. The numerical simulation results agree with the reported experiment data with a deviation of less than 10 %, which validates the accuracy of the model. This model provides a convenient and efficient approach for designing the high-beam-quality TDFLs with reduced experiment efforts.

“…Semiconductor optical amplifiers (SOAs) have been a subject of extensive research for a long time. Their principle of operation, recombination mechanisms and material gain has been thoroughly discussed in the literature [1][2][3][4][5][6][7][8][9]. Indeed, commercial photonic networks are heavily integrating these compact devices due to their broadband and homogeneous gain characteristics [10], fast transient time and high optical non-linearity [7].…”
