“…Thus, it can achieve efficient mode conversion, simple configuration and support more higher-order modes. In our prior work, a Sagnac interferometer with weakly coupled two-mode fiber (TMF) delay line has been proved to achieve multi-wavelength output simply and stably [6]. A continuous output all-fiber ring laser was also proposed to exhibit spatial mode switching [24], which is an efficient method to generate higher-order modes.…”

“…At a specific coupler diameter, the input fundamental LP 01 mode in the SMF arm can be switched into higher-order modes (e.g. LP 11 mode, LP 21 mode, LP 02 mode) in the FMF arm over a broad wavelength range of around 1550 nm when the propagation constant β 0 of the fundamental mode in the SMF is phase matched with the β 1 of the high-order mode in the FMF [6] DEMUX1. Mode crosstalk among the modes (LP 01 , LP 11 ) of mode MUX2/DEMUX2 is also analyzed, as shown in table 2.…”

“…Multi-wavelength fiber lasers have been widely discussed because of their potential applications in wavelength division multiplexing (WDM) optical communication systems [1,2], optical fiber sensing [3], optical spectroscopy [4] and microwave generation [5]. Meanwhile, erbium-doped fiber (EDF) as a gain medium has been widely employed in multiwavelength fiber lasers due to its low intensity noise, high output power and high compatibility [6]. As a result, various approaches have been reported to achieve multi-wavelength oscillation in EDF lasers.…”

We experimentally demonstrate an all-fiber erbium-doped fiber ring laser based on a Sagnac interferometer with a low modal crosstalk mode multiplexer/demultiplexer (MUX/DEMUX). Three linearly polarized (LP) modes are generated by mode MUX/DEMUX, which consists of cascaded mode-selective couplers. The proposed fiber laser can simultaneously achieve spatial-mode switching and multi-wavelength tuning. In the experiment, single-, dual-, and triple-wavelength lasing outputs for LP 01 , LP 11 , LP 21 and hybrid modes are obtained. The stabilities for LP 01 , LP 11 , LP 21 and hybrid modes are investigated in more than 20 min, 16 min, 12 min and 16 min, respectively. Moreover, the mode intensity profiles, the OSNRs of the lasing output and the slope efficiencies are also measured.

“…Therefore, the development of MWFLs is undoubted of great significance. The traditional filter structures, such as Mach-Zehnder interferometer [19], Fabry-Perot interferometer [20], Sagnac interferometer [21], Michelson interferometer [22], Lyot Filter [23], and different types of fiber gratings cascaded [24], have been demonstrated to achieve the tunable MWFLs. However, the limited tunability of these filters greatly hinders their applications.…”

We propose and demonstrate an effective and simple multi-wavelength spatiotemporal mode-locked (STML) laser. The laser introduces a multimode interference (MMI) effect using the core diameter mismatch of the fibers, thus enabling simultaneous mode-locking at multiple wavelengths. For the multi-wavelength mode-locking, each wavelength exists a matching pulse sequence, and different wavelengths can possess the same pulse state or different states. Meanwhile, at the dual-wavelength operation, by adjusting the polarization controllers, not only the central wavelength can be continuously adjusted from 1552.93 nm to 1572.64 nm, but also the wavelength interval can be adjusted from 2 nm to 19 nm, which benefits from the tunability of the MMI effect. Moreover, the spectral channels can be consecutively increased from 2 to 4. The obtained results provide a platform for understanding and studying the multi-wavelength STML properties. This flexible all-fiber laser has great potential for applications in the fields of optical signal processing, fiber sensing, and information coding.
