“…Notons que le confinement par bande interdite photonique présente la propriété de n'opérer que pour certaines longueurs d'ondes, ce qui permet d'écarter les longueurs d'onde indésirables comme, par exemple, celles générées par diffusion Raman, minimisant ainsi leur amplification. Ce concept peut également être appliqué à la réalisation de fibres VLMA telles que celles que nous allons découvrir à présent [3].…”

Les systèmes lasers fibrés sont au coeur de nombreuses recherches académiques et constituent un marché annuel mondial dépassant le milliard d’euros. L’augmentation de la puissance en sortie de ces dispositifs a été rendue possible grâce à une innovation permanente portant sur la géométrie de fibres, les matériaux qui les constituent et les méthodes de synthèse associées. Après un bref rappel historique, nous rappelons quelques éléments de contexte et présentons quelques avancées récentes en matière de fibres à très grandes aires effectives.

“…In recent years, people have proposed several fiber structures to achieve the requirement of single-mode operation in a large mode field area with good bending robustness, e.g., photonic crystal fibers [12][13][14][15][16][17][18], low numerical aperture (NA) step-index core fibers [19][20][21][22], Bragg fibers [23,24], multi-trench fibers [25][26][27][28][29], and leakage channel fiber [30][31][32][33] etc. However, these fibers have some problems.…”

In this paper, a novel fiber with a parabolic-profile core and eight segmented trenches in cladding is designed. The designed fiber consists of the segmented trench of low refractive index in cladding and parabolic-profile of high refractive index in the core. The proposed fiber has good bending resistance. The eight segmented trenches in the cladding can decrease the refractive index of cladding to increase the difference index between the core and cladding to limit fundamental mode (FM) loss. The proposed fiber can offer an effective single mode (SM) operation with a large mode area (LMA) of 952 µm2 at the small bending radius (R = 10 cm). In addition, the fiber is also suitable under an 18 W/m heat load. The proposed fiber achieves good bending performance, which can be suitable for the compact high-power lasers.

“…The most direct way to solve these problems is increasing the mode area to reduce optical power density [3]. Thus, many large mode area(LMA) fibers are designed, such as leaky channel fiber (LCF) [4], large-pitch fiber (LPF) [5], chirally coupled core (CCC) fiber [6], multicore fiber [7], photonic crystal fiber (PCF) [8], photonic bandgap fiber (PBGF) [9], multi trench fiber (MTF) [1,10], bragg fiber [11], distributed modal filtering rod fiber (DMF) [12], segmented cladding fiber (SCF) [13] core fiber [14], and gain-guided and index-antiguided (GG-IAG) fiber [15,16] et al These designed LMA fibers have been extensively applied in pulsed lasers and single-frequency lasers [4][5][6][7][8][9][10][11][12][13][14][15][16]. However, some of them, the core diameters are lower than 50 μm, or the fiber structure is very complicated and very difficult to fabricate.…”

Fabrication and Performance of a Heterogeneous-Helical-Cladding Fiber

et al. 2021

View full text Add to dashboard Cite

Large mode area (LMA) fibers are widely used in high power fiber lasers to solve the nonlinear problems. In this work, a Nd 3+ -doped phosphate glass LMA fiber with heterogeneous helical claddings (HHC) is fabricated successfully by rod in tube method for the first time. The performance of the preform glass was matched well and suitable for drawing the fiber, and the related fabrication method is helpful for other special structure fiber fabrication. The fiber performance such as loss and gain coefficients are both tested and compared respectively. The experiment results show that the loss coefficient α will increase with the decrease of Λ (helix pitch) or r (fiber core radius), furtherly, the net gain coefficient g will become larger with the increase of r or Λ. The experiment results are beneficial to the HHC fiber design furtherly. As the HHC fiber has an all-solid-state structure, it is easy to fabricate relatively and convenient for cutting, splicing, etc. Thus, the HHC fiber will have potential applications in the field of fiber lasers.
