The output characteristics of actively Q-switched ytterbium-doped fiber lasers (YDFL) are investigated in this paper. Our experimental results show that, the combined effect between the short switching time and the gain transient property of doped fi

We present an all-fiber sensor for simultaneous measurement of temperature and strain. The sensing head is formed by introducing a fiber Bragg grating into a high-birefringence fiber loop mirror that acts as a Mach-Zehnder interferometer for temperat

We report the comparisons of the influences of gain broadening on multiwavelength oscillations in YDFL and EDFL with typical commercial ytterbium- and erbium-doped Al/Ge silica fibers. Our experimental results show that both the YDF and the EDF exhib

In this paper, reflectivity characteristics of a fiber loop mirror (FLM), which is formed by inserting a fiber polarization controller (PC) into the fiber loop of an ordinary FLM, are investigated in detail. A theoretical model for determining the re

In this paper, we propose a novel mismatched multicavity etalon (MME) all-pass filter for fixed-value dispersion compensation and dispersion slope compensation. It is a multicavity Gires-Tournois (GT) etalon filter with unequal cavity lengths between

For applications in dense wavelength-division-multiplexing (DWDM) systems, optical periodic filters with a rectangular spectral response are highly desirable to maximize system performance. In this paper, optical periodic filters using a multi-reflec

This paper reports on a fiber laser constructed with an erbium-doped fiber, which has an elliptical core that is single-moded along the minor axis and multimoded along the major axis. The laser can simultaneously emit several stable lines at room tem

A ring erbium-doped fiber (EDF) laser with an additional EDF saturable absorber operating in the L-band can produce dual-wavelength optical bistability. The bistabilities of the two wavelengths evolves in antiphase; the dual-wavelength bistable behav

Multiwavelength oscillations in erbium-doped fiber (EDF) lasers with active overlapping linear cavities are investigated in detail. The laser can be designed to produce multiwavelength oscillations in the C-band and in the L-band. With a C-band three
