Ultrahigh effective mode area photonic crystal fibers with extremely low bending loss for long distance transmission application

Sensing and Bio-Sensing Research
In this work, an extremely large mode area (LMA) photonic crystal fiber (PCF) design has been proposed having single mode operation. A full-vectorial finite element method (FEM) approach is considered with perfectly matched layer (PML) boundary for ...

Design and Fabrication of Single Transverse Mode Passive Large-Pitch Fibers

Cumhuriyet Science Journal
The fabrication processes of single transverse mode passive large-pitch optical fiber (LPF) have been proposed and investigated. The LPF design, combined with the fundamental mode operating principle of delocalizing higher-order modes, has led to ...

Anti-Resonant Fiber with Large Mode Area and Ultra-High HOMER for Near-Infrared High-Power Laser

Photonics
A novel anti-resonant hollow-core fiber (AR-HCF) is proposed. The fiber uses cross-nested circular cladding tubes including single-nested and non-nested tubes in the near-infrared spectral region of 1.3–1.7 μm.

Polarization maintaining large mode area photonic crystal fiber

Optics Express, 2004
We report on a polarization maintaining large mode area photonic crystal fiber. Unlike, previous work on polarization maintaining photonic crystal fibers, birefringence is introduced using stress applying parts. This has allowed us to realize fibers, which are both single mode at any wavelength and have a practically constant birefringence for any ...

Multi-trench Fiber for high power laser applications

, 2014
Optical fibers have realized their immense potential for high power applications in the last decade. However, non-linearity still remains a challenge for power scaling for fiber lasers [1].

Extending single mode performance of all-solid large-mode-area single trench fiber [PDF]

, 2014
We report a novel "single trench fiber" design for mode area scaling of the fundamental mode while offering effective single mode operation for a compact fiber laser device.

Multimode-pumped Raman amplification of a higher order mode in a large mode area fiber.

Optics Express, 2018
We report the first demonstration of Raman amplification in a fiber of a single Bessel-like higher order mode using a multimode pump source. We amplify the LP08-mode with a 559-µm2 effective mode area at a signal wavelength of 1115 nm in a pure-silica ...

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.

Mode-multiplexed 16-QAM transmission over 2400-km large-effective-area depressed-cladding 3-mode fiber

, 2018
We demonstrate 2400 km mode-multiplexed 16-QAM transmission over a low DMGD (27.1 ps/km) and low MDL (1.75 dB) 3-mode fiber link. The large effective-area 3-mode fiber is shown to outperform a standard single-mode fiber for distances up to ...
