Temperature-Dependent Performance Optimization of a Filtered ASE Source Employing Low-Concentration Erbium-Doped Fiber

Quantum Beam Science
Research on the thermal stability of amplified spontaneous emission (ASE) has mostly focused on broadband spectra. High-precision fiber optic gyroscopes (FOGs), however, require spectrally filtered sources.

Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber

We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%

Investigation of Intra-Cavity SPR Sensor Based on Erbium-Doped Fiber Laser

IEEE Photonics Journal
In this paper, an intra-cavity SPR sensor based on erbium-doped fiber (EDF) laser is proposed to achieve higher sensitivity for detecting analyte refractive indices. A liquid-core fiber-based SPR sensor is first designed to match the operating wavelength

Single frequency erbium doped fiber laser with a highly doped erbium-doped fiber

, 2010
A single frequency Erbium-doped fiber laser (EDFL) operating at 1552.5 nm has been demonstrated by using a 2 m long of newly developed Zirconia-based Erbium-doped fiber (Zr-EDF) as a gain medium. The Zr-EDF is fabricated by combining Zr and Al to achieve

Regulating emission in Er doped silicate glass and fiber via coordination engineering

Journal of Materiomics
L-band Er doped fiber (EDF) laser sources are in great demand for extending communication bandwidth. However, the gain performance is limited by the low emission cross section (σe) of Er3+ at wavelengths longer than 1590 nm. In our study, we revealed the

Estimation of Erbium Doped Optical Fibers Effective Area

Erbium doped fiber amplifiers (EDFAs) are one of the most extensively used optical amplifiers in the fiber optics transmission systems. EDFA working principle is based on erbium doped fiber (EDF) application to amplify optical signal at wavelength region

Pump wavelength dependence of bismuth doped fibre laser

, 2008
We characterize Bi doped fibres in spectroscopic perspective under 915, 976 and 1090 nm pumping. The performance of Bi doped fibre lasers under different pumping bands is correlated to the spectroscopic characteristics.
