A fiber sensor based on Vernier effect for simultaneous temperature and strain
measurement is proposed and demonstrated, which consists of a Mach-Zehnder …

Fiber laser sensors have been present for almost four decades as versatile sensing devices
with a simple demodulation process, high sensitivity, and competitive resolution. This work …

Narrow-linewidth multi-wavelength fiber lasers are of significant interests for fiber-optic
sensors, spectroscopy, optical communications, and microwave generation. A novel narrow …

We propose and demonstrate a four-wavelength-switchable erbium-doped fiber laser (4WS-
EDFL) with a four-channel superimposed high-birefringence fiber Bragg grating (SI-HBFBG) …

This paper presents an axial strain laser sensing setup based on a core-offset Mach-
Zehnder interferometer (MZI). The core-offset MZI was implemented by fusion splicing of …

A highly sensitive liquid-level sensor based on dual-wavelength single-longitudinal-mode
fiber laser is proposed and demonstrated. The laser is formed by exploiting two parallel …

In this paper, we present a systematic study of ytterbium-doped pulsed fiber lasers, both Q-
switched and mode-locked, that emitted in switchable and tunable multi-wavelength states …

An improved erbium-doped fiber laser configuration for achieving single-polarization,
switchable dual-wavelength of orthogonal polarizations oscillations at room temperature is …

We report and demonstrate a highly-sensitive refractive index (RI) sensor based on a linear-
cavity dual-wavelength erbium-doped fiber laser (DWEDFL). The optical spectrum of the …
