“…In recent years, all kinds of multi-wavelength EDFLs have been proposed by different schemes, such as employing a large-core fiber filter [1], phase-shifted fiber Bragg grating combined with a Mach-Zehnder interferometer [2], a Sagnac loop and tunable filter [3], a four-mode fiber Bragg grating (FBG) [4], a core-offset Mach-Zehnder interferometer with non-zero dispersion-shifted fiber [5], graphene/PMMA thin film [6] or a fiber Michelson interferometer [7]. However, the above MWFLs often have some disadvantages, such as a complex loop cavity structure that causes low slope efficiency, greater welding loss for the mismatch of the fiber core and toolong fiber length.…”

A switchable triple-wavelength erbium-doped fiber laser based on a fiber Bragg grating filter (FBGF) and C-band 50 GHz interleaver is proposed and demonstrated experimentally at room temperature. The FBGF alone can only excite unstable multi-wavelengths. To obtain a stable multi-wavelength output, an interleaver with stationary wavelength spacing and the polarization hole burning effect are used; finally, the laser can switch flexibly to output three different modes from single-or dual-to triple-wavelength. All of the lasing lines with narrow linewidths have the optical signal-to-noise ratio of more than 20 dB, and locate at the wavelength positions in the range of about 1530 nm to 1533 nm. The laser with good light-intensity uniformity shows better stabilities with respect to the wavelength and peak power.

“…Thus, compared with single wavelength laser, wavelength switchable laser is more convenient and cost efficient. Besides the wavelength switchable continuous-wave (CW) lasers [3]- [5], the wavelength switchable mode-locked lasers generating high-power and ultra-short optical pulses are desirable light sources for time/wavelength division multiplexing optical communication systems [6], [7]. Furthermore, the high-intensity pulsed beam can result in nonlinear effects and photo-luminescence effects, thus it can also be widely used in spectroscopy [8], optical signal processing [9] and so on.…”

Wavelength Switchable Mode-Locked Fiber Laser With Tapered Two-Mode Fiber

We propose and demonstrate a wavelength switchable mode-locked Erbiumdoped fiber laser with carbon nanotubes for mode-locking and a tapered two-mode fiber (TTMF) based filter for wavelength selection. The TTMF based filter constructed with singlemode fiber-TTMF-single-mode fiber configuration, features smooth interference spectrum. It is attributed to that only two modes are involved into the interference in the specially designed TTMF, which is confirmed by both simulations and experiments. Moreover, the free spectral range (FSR) of the TTMF based filter can be arbitrarily chosen by controlling the taper diameter. Depending on the FSR of the TTMF based filter, the central wavelengths of the mode-locking operation of the Erbium-doped fiber laser based on carbon nanotubes can be switched between two wavelengths with FSR of 8.5 nm and three wavelengths with FSR of 3.1 nm, respectively. This fiber laser is flexible source for various applications.
