“…The most common is adding a wavelength-dependent filter within the laser cavity to modulate the cavity losses and induce emissions at wavelengths with minimal losses and considerable gain. These wavelengthdependent filters are often based on interferometric structures such as Michelson [4,5], Mach-Zehnder [6], Fabry-Perot [7], and Zagnac [8] interferometers. One of the most used and suitable for many applications interferometer is the Mach-Zehnder interferometer, it has been manufactured for example with gratings [9], tapers [10], photonic crystal fiber [11,12], twin-core fiber [13], and multi-core fiber [14,15].…”

Tuning of optical fiber laser emissions based on super-mode interference in a seven core fiber (SCF) is presented. This super-mode interference is generated by a super-mode Mach–Zehnder interferometer constructed with a few millimeters of SCF spliced between two single mode fibers (SMFs). In the SCF, two super-modes are exited via the fundamental mode of the SMF. Then, an interference pattern caused to the optical path difference between super-modes is generated at the final of the SCF, which is collected with the spliced SMF. This interference pattern induces and tunes laser line emissions by adjusting the laser cavity losses in an optical fiber laser. By bending the Mach–Zehnder interferometer, a wavelength shift of the interference pattern is induced, which in turn causes a wavelength shift of the laser cavity losses and, therefore, a displacement of the laser wavelength emission. Laser line emissions were tuned by linear factors of around 0.91 nm mm−1, and the switching of simultaneous emissions was also obtained. The stability and reliability of the laser emission on the proposed method are also discussed.

“…In recent years, multi-wavelength output lasers are often achieved with multi-wavelength filters. These filters usually consist of special structures to achieve interference effects, thus achieving multi-wavelength laser output, such as Michelson [9][10] , Mach-Zendel [11] , Fabry-Perot [12] , and Zagnac [13] interferometers. Mach-Zendel interferometer is one of the most used and widely used interferometers, and has been fabricated for gratings [14] , pull cones [15] , photonic crystal fibers [16] , multi-core fibers [17][18] , etc.…”

A triple-wavelength erbium-doped fiber laser based on seven-core fiber (SCF) interferometer is proposed and successfully implemented. In the structure of the laser, a special structure of single-seven-single core is used to realize laser interference, which is composed of a 6 cm SCF and ordinary fiber optic patch cables fused by convex cone. In the laser with simple structure, triple-wavelength output with central wavelengths of 1530 nm, 1544 nm and 1558 nm are obtained by adjusting the polarization controller, and the optical signal-to-noise ratio (OSNR) of the triple-wavelengths is approximately 60 dB. The laser has high stability in terms of both wavelength and power. In the stability test of 150 min, the frequency drift of three wavelengths is approximately 0.4 nm, and the output wavelength peak power jitter is approximately 1.6 dB. The laser has the characteristics of simple structure and high stability, and has broad application prospects in the fields of optical fiber sensing, wavelength division multiplexing (WDM) optical communication system and microwave photonics.

“…For example, to induce many emissions, filters with periodical wavelength-dependent losses (comb filter), in which the emissions may be produced at the maxima of the transmission spectrum of the filter [13], have been employed to generate multi-wavelength optical fiber lasers. For instance, comb filters based on the Fabry-Perot [14][15][16], Mach-Zehnder [17,18], Michelson [1,[19][20][21] and Sagnac [22] interferometers have been added to optical fiber cavity lasers to induce and control multiple laser emissions. The Fabry-Perot interferometer has been widely utilized since it is an excellent sensitive optical fiber device.…”

The shaping of the output laser by using a modifiable intra-cavity filter, which is based on a reconfigurable Fabry–Perot interferometer, is experimentally demonstrated. This output shaping method is carried out using a Fabry–Perot interferometer formed by the partially reflected faces of two single-mode fibers (SMFs). The two SMF ends are inside a capillary glass, where one is fixed, and the other one can be linearly displaced. As the free fiber is displaced, the separation distance between the planar faces is modified, which changes the interferometer properties to allow the adjustment of the laser intra-cavity losses to shape the output laser. The shaping of the output laser is focused on varying the wavelength peak number that may induce laser emissions and also shift these peaks. For the laser setup used in this work, a maximum of four simultaneous laser emissions was achieved. In addition, the experimental results for a constant interferometer separation distance provide emissions with negligible variations.
