“…Fiber lasers play a crucial role as light sources in wavelength-division multiplexed (WDM) fiber communication systems, as well as in optical detection and optical signal processing applications [1,2]. A wavelength-switchable fiber laser often proves more versatile and efficient than a fixed-wavelength fiber laser in various applications such as wavelength protection, optical measurement and wavelength routing [3,4].…”

A spacing-adjustable and switchable multi-wavelength erbium-doped fiber laser is proposed and analyzed based on the polarization hole burning (PHB) effect. The comb filter consists of multimode fiber - polarization maintaining fiber - multimode fiber (MMF-PMF-MMF). Here the filter is used as the polarization-dependent element to induce the polarization hole burning (PHB) effect. The filter is placed in the laser cavity or embedded into the Sagnac loop. By adjusting the polarization controller (PC) in the cavity, when the filter is placed in the laser cavity, the output wavelengths can be switched from single-wavelength to sextuple-wavelength, and dual-, triple-, quad-, quintuple- and sextuple-wavelength with adjustable wavelength spacing can be obtained. The dual-wavelength has a substantial amount of wavelength spacing adjustability with the range of 3.32 nm to 30.16 nm. When the filter is embedded into the Sagnac loop, the wavelength tuning ranges for single-, dual-, triple- and quad-wavelength are 28.42 nm, 28.10 nm, 18.21 nm and 14.58 nm, respectively. The proposed erbium-doped fiber laser (EDFL) provides a wide range of wavelengths and adjustable spacing, which is suitable for a variety of applications such as optical communication, optical detection and optical signal processing.

In this work, a single and dual-wavelength erbium-doped fiber laser (EDFL) based on two Mach-Zehnder interferometers (MZIs) in cascade structure was experimentally validated. MZIs were assembled by joining a capillary hollow-core fiber (CHCF) piece between two multimode fibers (MMFs) sections. The switchable operation is reached by moving the spectrum of one MZI when the temperature is increased. The maximum measured signal noise to ratio (SNR) was more than 50 dB for the single and dual-wavelength laser lines. Besides, stable output is shown since no power and wavelength variations were noticed. It is important to mention that emissions are obtained at precise wavelength positions and not arbitrarily as described by other investigations. This EDFL can be used in applications of optical fiber communications systems and fiber sensing.

Compared with other lasers, fiber laser is widely used in optic communication, industrial production, biomedical sciences, and other fields because of its excellent technical performance, low manufacturing cost, mature technology, high conversion efficiency, high stability, and many other advantages. Recently, two new optical fiber communication techniques that are quickly evolving are Wavelength Division Multiplexing (WDM) and Dense Wavelength Division Multiplexing (DWDM). As a result, multiwavelength and wavelength-tunable fiber lasers were created to address the demand for optical communication systems with high throughput, high quality, and high speed. Due to their advantages in lowering equipment complexity, enhancing network flexibility, enhancing fiber system integration, etc., switching dual-wavelength fiber lasers based on Array Waveguide Grating (AWG) have received a lot of attention. This paper studies two switching dual-wavelength fiber laser based on AWG. Firstly, the basic structure of Erbium-doped Fiber Laser (EDFL) is analyzed based on the basic principle of Erbium-Doped Fiber (EDF). In addition, the working principle of AWG is analyzed emphatically. Finally, AWG-based switching dual-wavelength fiber lasers in linear/ring cavity, which achieve that the adjustable wavelength intervals between 0.8nm to 12nm, are verified and discussed experimentally. Additionally, experimental data shows that the dual-wavelength lasing power is stable and equal.
