Simultaneous Ce Ion Doping in Core and Cladding to Enhance the Radiation Resistance of Erbium-Doped Fibers

Photonics
Erbium-doped fibers (EDFs) suffer from radiation-induced absorption (RIA) and radiation-induced gain variation (RIGV) under ionizing radiation, which limit their applications in space optical communication systems.

Experimental Measurement of Absorption Coefficients for Effective Erbium-Doping Concentration to Optimize Few-Mode Erbium-Doped Fiber Amplifiers with Low Differential Mode Gain

Photonics, 2021
According to the analytical expression for modal gain of few-mode erbium-doped fiber amplifiers (FM-EDFAs), we propose a method of measuring the absorption loss coefficients of few-mode signals in few-mode erbium-doped fibers (FM-EDFs) by extrapolating ...

Polarization‐Controlled Wavelength‐Tunable Pulsed Laser Based on Metafiber

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A polarization‐sensitive Au‐nanorod metasurface has been proposed that integrates saturable absorption with wavelength‐tuning capabilities. By fabricating this metasurface structure on the facet of the fiber, known as a metafiber, low‐loss coupling between the metasurface and the fiber laser system is achieved.
