“…Yin. et al reported a tunable DW-EDFL by adopting twin-core fiber (TCF) and achieved tunable bandwidth of 1.2 nm with the SMSR higher than 40 dB [16]. A four-wavelength switchable fiber laser based on twin-core EDF is achieved by Lian with a wavelength spacing of 1.1 nm and the SMSR higher than 43 dB [17].…”

“…A commercial splicer (Fujikura, FSM-100M) is used to splice one end of TCPCF with SMF using the core-to-core splice mode built in the machine. At the other end of TCPCF, we use the splice method depicted in [16] to monitor the output power in real-time. When it gets maximum, the lead-in and lead-out SMFs are aligned to the same core of TCPCF.…”

Based on tapered Triple-Core Photonic Crystal Fiber (TCPCF), a high performance tunable Dual-Wavelength Erbium-Doped Fiber Laser (DW-EDFL) is proposed and experimentally demonstrated. The mode-coupling among three cores of TCPCF appears periodically and becomes further enhanced in tapered TCPCF, which are beneficial to form a filter to select lasing wavelength. A series of tapered TCPCFs with different taper lengths are fabricated and inserted into tunable DW-EDFL as filters. Multiple groups of tunable dual-wavelength lasing outputs are achieved by using the tapered TCPCF filter with a waist diameter of 126 μm. The maximum tunable range can reach up to 14.36 nm and the side mode suppression ratio of all lasing outputs are above 52 dB. In addition, the tunable single-and triplewavelength lasers are also obtained. The tunable single-wavelength laser has an excellent linear response to strain and can be applied to realize a high-sensitivity strain sensor with the highest strain sensitivity of-13.1 pm/με.

“…They demonstrated a tunable output laser line with 32 nm tuning range. Dual-wavelength EDFL with tunable wavelength spacing has been achieved using twin core [17], tapered EDF [18] and non-linear photonic crystal fiber (NLPCF) [10]. In [3,[19][20][21], stable multi-wavelength laser emission was obtained using in-line NLPCF MZI but with variable wavelength spacing.…”

A high output power, stable wavelength spacing and switchable multi-wavelength erbiumdoped fiber laser has been demonstrated experimentally using a combination of non-linear photonic crystal fiber Mach-Zehnder (MZI) interferometer with polarization dependent loss effect. This MZI functions together with a polarization controller (PC) as a wave selecting filter (WSF). Adjusting the PC within the WSF part gives rise to three emissions as single, dual and triple wavelengths. Multi-wavelength laser with maximum spacing of 1.6 nm was achieved by controlling the polarization state in a ring cavity. Such stable wavelength spacing aroused interest in wavelength-division-multiplexer systems. Output power around −3 dB at 1550 nm wavelength, with small power fluctuation for each line, was recorded at room temperature. The measured 3-dB laser line-width was 0.03 nm, with a high side-mode suppression ratio of 48 dB.

Tunable fibre lasers draw intensive attention because their emission wavelength can be systematically tuned within a certain spectral range, which allows using a single laser source instead of several sources. This is convenient and cost-effective for many applications in a range of fields, such as telecom, material processing, microscopy, medicine and imaging and so on. The laser wavelength can be tuned in a certain range of wavelength by inserting wavelength-selective elements into the laser's optical cavity. This chapter describes the twin core fibre (TCF)-based filters, which work as the wavelength-selective element. They are introduced into the ring cavity to implement tunable single-, dual-and multi-wavelength fibre lasers. First, we deduced the coupled-mode theory of TCF-based filter. Second, we experimentally and numerically characterized the optical properties of TCF-based filters including free spectral range, polarization dependence, strain effect and bending effect. Finally, we investigated three tunable fibre lasers which operate at single-, dual-and multi-wavelengths, respectively. The operation mechanism of the fibre lasers mainly involved the elastic-optic effect, polarization hole burning effect and non-linear optical loop mirror. We emphasized the tuning mechanism and the tuning characteristics of the tunable fibre lasers.
