Fiber cavities with integrated mode matching optics [PDF]

Scientific Reports, 2017
In fiber based Fabry-Pérot Cavities (FFPCs), limited spatial mode matching between the cavity mode and input/output modes has been the main hindrance for many applications. We have demonstrated a versatile mode matching method for FFPCs. Our novel design

Single-Mode ZBLAN Fiber Couplers [PDF]

EPJ Web of Conferences, 2022
We demonstrate single-mode ZBLAN optical fiber couplers. A controlled tapering procedure leads to coupling ratios of 5%/95% and 14%/86% at a wavelength of 2200 nm, with insertion losses of 1.6 dB and 1.8 dB, respectively.

Investigation of a Large-Mode-Area Fiber Designed for 2.0 μm Based on Multi-Layer Holes Resonance

IEEE Photonics Journal, 2023
This work proposes a novel large mode area fiber with multi-layer holes of 2.0 μm based on electromagnetic field theory and finite element analysis. Modifying the structure parameters can reduce the fundamental mode confinement loss to less than 0.

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core

Photonics, 2022
We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

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.
