“…Certain filters rely on interference principles, such as Fabry-Perot interference (FPI), Mach-Zehnder interference (MZI), Sagnac interference (SI) and mode interference (MI) [14]. Interference-based filters have a more straightforward design [15] and are cost-effective when compare to grating-based filters, making them well-suited for MWEDFL applications due to their sensitivity, adaptable structure, and uncomplicated setup [16], especially for filters based on MZI. In 2021, Zijuan Tang et al demonstrated by using a 10.5 cm long four-leaf clover suspended core fiber filter, which was fabricated by splicing a 10.5 cm long FLCSCF.…”

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.
