Large mode area double-layer all-solid anti-resonant fiber for high-power fiber lasers

Results in Physics, 2021
A novel double-layer all-solid anti-resonant fiber (DL-AAF) is proposed to develop large mode area (LMA) fiber for high-power fiber laser applications. Single-mode property and mode field area scaling are investigated in simulations. Numerical results show the fiber can achieve strong suppression of higher order modes (HOMs) even with a large core size.

Single polarization single mode THz hollow-core anti-resonant waveguide with multi-size semi-elliptical tubes and high-resistance silicon layer

Results in Physics
We present the design of a Single Polarization Single Mode (SPSM) Terahertz Hollow-Core Anti-Resonant Waveguide (THz HC-ARW) by using multi-size semi-elliptical tubes (SETs) and high-resistance silicon layer. High single mode performance can be achieved by optimizing the structural parameters in the structure of the THz HC-ARW with multi-size SETs in ...

Optimization of Low-Loss, High-Birefringence, Single-Layer, Annular, Hollow, Anti-Resonant Fiber Using a Surrogate Model-Assisted Gradient Descent Method

Photonics
This paper proposes a novel optimization method for hollow-core, anti-resonant fiber based on a gradient descent algorithm assisted via a radial basis-function surrogate model. This approach significantly reduces the number of optimization iterations, achieving a stable improvement in birefringence performance by an order of magnitude across the ...

Hybrid hollow-core polarization-maintaining fiber with high birefringence and wide single mode bandwidth

Results in Physics, 2021
A novel hybrid hollow-core polarization-maintaining fiber is proposed by combining the photonic bandgap mechanism and anti-resonant effect. High birefringence can be achieved by introducing a pair of negative curvature anti-resonant layers into the air ...

High birefringence single-polarization composite structured anti-resonant fiber

Results in Physics, 2023
We propose a highly birefringent, single-polarization composite structured anti-resonant fiber (CS-ARF). The proposed CS-ARF has an elliptical core, two symmetrically spaced arrays of elliptical air holes, and a six-tube anti-resonant structure.
