Standard Single-Mode Fiber with High Modal Bandwidth as Two-Mode Fiber around 1060 nm for High Data Rate Transmission

open access: yesPhotonics, 2023
A step-index standard single-mode fiber as a two-mode fiber at 1060 nm can have a high modal bandwidth. In the current work, we conducted a detailed study and found that the LP11 mode of such a fiber is bending-sensitive and that the light excited to ...

Birefringence for Elliptical-Core Fibers with Low Ellipticities

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2022
Model birefringence was measured for elliptical-core fibers with low ellipticities, note the birefringence depends strongly on the frequency, especially when fiber is being operated near the higher mode cutoff where ν  for circular fiber of the single ...

Spatial mode switchable, wavelength tunable erbium doped fiber laser incorporating a spatial light modulator [PDF]

open access: yes, 2014
We present a 2-mode group, switchable spatial mode erbium doped fiber laser incorporating a spatial light modulator. The laser wavelength can be tuned using an intra-cavity wavelength selective filter and provides >10dB extinction ratio between LP01 ...

High Efficiency Coupling Technology of Silicon Photonic Modulator and Single-Mode Optical Fiber

open access: yesGuangtongxin yanjiu, 2021
Due to the small mode field of silicon photonic chips, the large coupling loss is a road-blocker for their applications. In this work, the coupling efficiency between a silicon photonic modulator chip and a single-mode optical fiber is investigated.

All Solid Multistep-Index Core Large Mode Area Single-Mode Fiber

open access: yesIEEE Photonics Journal
In this paper, a large-mode-area (LMA) single-mode fiber based on multistep-index core structure is proposed. The multistep-index core increases the mode field area (MFA).
