Low-loss criterion and effective area considerations for photonic crystal fibers [PDF]
, 2003 We study the class of endlessly single-mode all-silica photonic crystal fibers with a triangular air-hole cladding. We consider the sensibility to longitudinal nonuniformities and the consequences and limitations for realizing low-loss large-mode area ...

Influence of Pedestal Fiber Splice on Tm-Doped Fiber Laser Performance
IEEE Photonics Journal, 2023 The influence of Tm-doped pedestal fiber splice on the output performance of a large-mode-area (LMA) Tm-doped fiber laser (TDFL) has been investigated. Arc-fusion induced refractive-index deformation leads to laser leakage from the core to the pedestal ...

Large mode area microstructured fiber supporting 56 super-OAM modes
Optics Express, 2019 In this paper, a kind of super-mode orbital angular momentum microstructured fiber (SM-OAM-MSF) is proposed. By introducing 20 Ge-doped equiangular cylindrical inclusions in the ring-core region, mode coupling mechanism is employed in the formation of super-OAM (SOAM) modes.

Characteristics of Collimators Based on the Large-Mode-Area CMCF for Coupling Laser Beam
Applied Sciences, 2021 A new collimator based on a homemade concentric multilayer-core fiber (CMCF) is proposed and experimentally demonstrated. This collimator was fabricated using a tail fiber with large mode area and single-mode operation.

Predicting macrobending loss for large-mode area photonic crystal fibers
, 2004 We report on an easy-to-evaluate expression for the prediction of the bend-loss for a large mode area photonic crystal fiber (PCF) with a triangular air-hole lattice. The expression is based on a recently proposed formulation of the V-parameter for a PCF

Spontaneous decay rates in active waveguides [PDF]
, 2005 We present a new method to measure the guided, radiated and total decay rates in one-dimensional waveguides. It is also theoretically shown that large modifications of the total decay rate can be achieved in realistic EDFAs and EDWAs with effective mode ...

158µJ pulses from a single transverse mode, large mode-area EDFA
, 1997 We report the amplification of 10pJ-100pJ, semiconductor diode pulses up to an energy of 158µJ and peak powers >100kW in a multi-stage fibre amplifier chain based on a single-mode, large mode-area erbium doped amplifier design. These results represent
