Mode selective photonic lantern integrated in a few mode erbium-doped fiber amplifier

, 2016
In the last decades, the development of the optical fiber technology has allowed increasing its transmission capacity roughly “ten times”. In the early stages, the data transmission was carried out over one single mode (or standard step index) fiber and ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Inverse scattering designs of dispersion-engineered single-mode planar waveguides

We use an inverse-scattering (IS) approach to design single-mode waveguides with controlled linear and higher-order dispersion. The technique is based on a numerical solution to the Gelfand-Levitan-Marchenko integral equation, for the inversion of ...

Mode Splitting Based on Polarization Manipulation in Few-Mode Fiber

, 2018
We report a mode splitting technique for LP01 and LP11 modes based on polarization manipulation in a few-mode fiber (FMF) by using a three-paddle two-mode fiber polarization controller (TMPC).

Simultaneous Beat-Length Measurement of a Polarization-Maintaining Few-Mode Fiber

IEEE Photonics Journal, 2019
Based on the polarization interference technique, we propose a modified method for simultaneously measuring the beat length of all guided modes in a polarization-maintaining few-mode fiber (PM-FMF).

Microstructured cladding elements to enhance performance and flexibility of large mode area leakage channel fibers

Large mode area fibers are imperative for scaling up the average power of fiber lasers. Single-mode behavior and low FM loss are the crucial functionalities for these fibers.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Generation of High-Quality Cylindrical Vector Beams from All-Few-Mode Fiber Laser

Photonics
Transverse mode control of laser intracavity oscillation is crucial for generating high-purity cylindrical vector beams (CVBs). We utilized the mode conversion and mode selection properties of two-mode long-period fiber gratings (TM-LPFGs) and two-mode ...
