Multi-wavelength lasing oscillations in an erbium-doped fiber laser using few-mode fiber Bragg grating

Abstract

We propose a simple erbium-doped fiber laser configuration for obtaining multi-wavelength oscillation at room temperature, in which a few-mode fiber Bragg grating was used as the wavelength-selective component. An amplitude variation of 1.6 dB over 120 second period was obtained for three-wavelength oscillation at room temperature, which demonstrates stability of the output power. This multi-wavelength laser can be switched between dual- and triple-wavelength operations by properly adjusting polarization controller in the cavity. This multi-wavelength laser has the advantage of simple configuration, high stability, low cost and stable operation at room temperature.

Multiple wavelength generation using a compacted hybrid Raman / Bi-EDF amplifier

“…These multiple wavelength lasers have been generated by various approaches such as immersion of EDF in liquid nitrogen and twin core EDF lasers [1], amplified spontaneous emission slicing [2], introducing four-wave mixing [3], and the usage of ultra-narrow bandpass filter as dual-phase-shift fiber gratings with ultra-narrow transmission bands [4].…”

Multi-Wavelength Fiber Optical Parametric Oscillator Based on a Highly Nonlinear Fiber and a Sagnac Loop Filter

“…Fiber lasers are one kind of the most important lasers, which also include multi-wavelength fiber lasers (MWFLs) with a huge potential in applications such as WDM optical communication systems, optical fiber sensors, optical component testing, microwave photonics and spectroscopy [20][21][22][23]. A great variety of MWFLs have been well developed based on various optical amplifiers including Erbium-doped fiber amplifiers (EDFAs) [24][25][26][27][28][29], fiber Raman amplifiers (FRAs) [30][31][32][33], fiber Brillouin amplifiers (FBAs) [34][35][36] and semiconductor optical amplifiers (SOAs) [37][38][39][40] in the past several years. Thereinto, multi-wavelength Erbium-doped fiber lasers (MW-EDFLs) have been widely investigated due to their advantages such as low cost, low threshold, high power conversion efficiency and compatibility with the optical fiber communication system.…”

Wavelength-spacing continuously tunable multi-wavelength SOA-fiber ring laser based on Mach–Zehnder interferometer

“…Multi-wavelength lasing has been achieved with various gain mediums including erbium-doped fiber amplifier (EDFA) [1][2][3][4][5], fiber Raman amplifier (FRA) [6][7] and semiconductor optical amplifier (SOA) [8][9][10]. Among them, SOA-fiber laser has been regarded as a potential and prosperous solution with several important advantages such as the stable multi-wavelength operation at room temperature, the broad workable wavelength band, and no need of optical pump lasers.…”
