Extra-Large-Mode-Area Few-Mode Laser Fiber
Asia Communications and Photonics Conference 2016, 2016An Yb-doped extra-large-mode-area few-mode laser fiber was fabricated successfully by chelate precursor doping technique. With refractive index difference of 0.0004 and numerical aperture of 0.036, the $25-\mu \text{m}$ -core fiber possesses extra-large-mode-area and few-mode properties.

Measuring bend losses in large-mode-area fibers
SPIE Proceedings, 2015We investigate the measurement of bend losses in few-mode large-mode-area (LMA) fibers. The influence of the light source spectral characteristics, modal power content and cladding light on the measurement accuracy and precision is studied experimentally. Monte-Carlo simulations are performed to understand the distribution of the variations. This study

Bending insensitive large mode area photonic crystal fiber
Optik, 2011A novel kind of large mode area photonic crystal fibers (PCFs) are proposed in this paper. In order to achieve large effective mode area, a novel technique is applied to seven missing air hole PCF structures. The modal characteristics of PCF structures such as effective mode area, confinement loss, chromatic dispersion properties with doped cores, are ...

Design of large mode area, mode selection fiber
SPIE Proceedings, 2014The paper study on the effect of index distribution on the mode field and calculated the mode distribution in various index profiles. A single mode gaussian hybrid multicore fiber with 19 hexagonally arranged high index quartz rods is designed and investigated. Theoretical and simulative results are presented and compared to the conventional large mode

Large mode area fibre designs for micromachining applications
SPIE Proceedings, 2010High power, high-energy, rare-earth-doped fiber laser sources are now considered a suitable option for a number of applications in Medicine, Telecom, LIDAR and industrial applications. Regarding the generation of high-energy pulses, there is a compromise between gain volume and M2 value or beam parameter product for the generation of pulses with ...

Bend distortion in large mode area fiber amplifiers
OECC/ACOFT 2008 - Joint Conference of the Opto-Electronics and Communications Conference and the Australian Conference on Optical Fibre Technology, 2008As ever larger mode area fibers are designed and incorporated into high-power amplifiers, bend-induced mode distortion becomes an important limitation. In any reasonable coiled-fiber arrangement, bend distortion can reduce mode area, gain interaction, and suppression of higher-order modes.

Broadband and large mode-area on-chip amplifier
2023Here, we present work towards a thulium-doped on-chip ultrafast amplifier, leveraging large mode-area gain waveguides with tailored group-velocity dispersion. We demonstrate 10 dB net gain for a broadband signal at 1820 nm inside a 5 cm-long waveguide.
