“…The commonly used methods to tune multi-core fiber interference filters are stretching and bending. In 2011, G. Lin et al [40] proposed a filter based on TCF, where three TCF filters were cascaded to optimize the transmission spectrum of the filter. By applying tension to the filter, the central wavelength of the filter could be adjusted in the range from 1540.8 nm to 1557.8 nm.…”

Tunable fiber lasers have the advantages of good beam quality, high integration, and adjustable output wavelength, and they are widely used in fields such as optical fiber communication and optical fiber sensing. The fiber filter is one of the key components of tunable fiber lasers. Among the various filters currently used, multimode interference filters have the advantages of simple structure, convenient implementation, flexible tuning methods, and convenient spectral range design. The structures of multimode interference filters based on multimode fibers, no-core fibers, multi-core fibers, tapered fibers, and other special fibers are introduced in this paper. The working principles and tuning methods are analyzed and the research progress of tunable fiber lasers based on these filters is summarized. Finally, the development trend of tunable fiber lasers based on multimode interference filters is discussed. The rapid development and applications of multimode interference filters can help improve the performance of continuous and pulse lasers as well as promote the practicality of tunable fiber lasers.

“…Numerous related schemes and fabrication techniques have been proposed in the past few decades, including fiber gratings [1][2][3], microsphere-and microfiber-loop-based resonators [4,5], in-line modal interferometers [6][7][8], and fiber taper coupler [9], etc. The spectral tunability of all-fiber optical filters could be fulfilled by exploiting the change of fiber intrinsic properties through acousto-optic effect, thermo-optic effect and photo-elastic effect.…”

Abstract-In this paper, an all-optically tunable filter based on laser-induced thermal effect has been proposed by employing a fiber taper coupler immersed in the magnetic fluids. Tunable spectral characteristics of the optically controlled fiber filter have been theoretically analyzed and experimentally investigated. Experimental results indicate that as the pump power varies from 0 mW to 216.1 mW, the proposed filter shows a large wavelength shift of 58.2 nm. Moreover, it exhibits a nonlinear spectral shift behavior in response to the applied pump light intensity with good spectral repeatability. With such desirable advantages as compactness, ease of fabrication, and high spectral tunability, our proposed all-optically tunable filter would be a promising candidate for fiber laser and amplification, fiber-optic sensing and optical fiber communications applications.
