“…10 In this regard, the semiconductor optical amplifier (SOA) is a potential alternative gain media for the development of multiwavelength fiber lasers (MWFLs). Unlike rare-earth doped fibers, SOAs are inhomogenously broadened gain media, [11][12][13][14][15][16] and thus able to minimize laser mode competition while at the same time having highly desirable characteristics such as being compact and light as well as consuming low power and can be mass produced. 2 SOAs can also be used for optical switching and wavelength conversion applications, which are highly useful characteristics for MWFLs.…”

A configurable, triple wavelength fiber laser based on broadband mirrors (BBMs) and an arrayed waveguide grating (AWG) is demonstrated. The laser uses a semiconductor optical amplifier (SOA) as the primary gain medium due to its inhomogeneous broadening property that allows for the generation high intensity lasing wavelengths. The combination of the AWG and BBMs allows for triple lasing wavelength outputs with channel spacing from 0.8 to 4.0 nm to be obtained. The generated output is adjustable between 1540.6 and 1548.6 nm. The proposed SOA‐based system is stable and can be used as a reserve laser source for wavelength division multiplexing systems.

“…Multiwavelength fiber lasers possess the merits of high coherence and wavelength switchability. Many ways have been put forward to develop multiwavelength fiber lasers, such as the Mach-Zehnder interferometer [21], the Lyot-Sagnac filter [22], superimposed chirped fiber Bragg gratings [23] and so on. Regarding multiwavelength TDFLs, Zhao et al reported a double-, triple-and quadrupling-wavelength switchable laser, using a multimode optical fiber to form the spatial mode competition filter [24].…”

We experimentally demonstrate a switchable multiwavelength thulium-doped fiber laser with cylindrical vector beam (CVB) emission, which is the first report, to our best knowledge, on the generation of CVBs in a 2 µm wavelength band. The Sagnac loop filter, made up of a 50:50 coupler, a section of polarization-maintaining fiber and a polarization controller, serves as a periodical filter and accounts for the excitation of multiwavelength channels. The mode-selective coupler consisting of both tapered single-mode and four-mode fibers has been designed and fabricated as a mode converter from LP 01 to LP 11 mode with a purity of >80%. By adjusting the polarization controllers, laser outputs with 1-3 switchable wavelengths have been realized in the spectrum ranging from 1988-1998 nm. The laser could find miscellaneous applications in wavelength/mode-division multiplexing system, etc.

“…Due to the homogeneous gain in EDF, multi-wavelength operation can be difficult to achieve. Many techniques have been put forward to overcome this problem, including as cooling of the fiber, using a phase modulator and an in-line comb filter, frequency shifted feedback, photonics crystal fiber and by controlling the cavity loss [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Multi-wavelength fiber laser in the S-band region using a Sagnac loop mirror as a comb generator in an SOA gain medium

et al. 2010

A simple design of multi-wavelength generation in the S-band region of the optical network transmission is proposed. The design consists of broad-band fiber Bragg grating (BB-FBG), which acts as a filter to enhance operation in the S-band region. A Sagnac loop mirror (SLM) is used to generate multiple wavelength oscillations in the ring cavity. The output consists of 60 lasing wavelengths oscillating simultaneously between 1464 nm and 1521 nm with a spacing of 0.92 nm and an output linewidth of 0.66 nm.
