In this experimental paper, a multi-wavelength erbium-doped ring fiber laser based on an all fiber intrinsic Fabry–Perot interferometer is presented and demonstrated. The interferometer was fabricated by an arc and splicing technique using hollow core photonic crystal fiber (HCPCF) and conventional single mode fiber (SMF28). The fiber laser can be operated in single, dual and triple lasing mode by applying a transversal load over the all fiber interferometer. The laser spectrums present minimal mode spacing of 1 nm, high wavelength stability and power fluctuations around 0.5 dB. The average signal to noise ratio (SNR) of the laser emissions spectrum is around 35 dB. This fiber laser offers low cost, compactness and high wavelength stability.

A single-/dual-wavelength switchable and tunable erbium-doped fiber laser (EDFL) with super-narrow linewidth has been proposed and experimentally demonstrated at room temperature. The fiber laser is based on a compound cavity simply composed of a ring main cavity and a two-ring subring cavity (TR-SC). Regardless of single-or dual-wavelength operation, the EDFL could always work well in single-longitudinal-mode (SLM) state at every oscillating wavelength. In dual-wavelength operation, the spacing could be tuned from 0 nm to 4.83 nm. In single-wavelength operation, the EDFL could lase at a fixed wavelength of 1 543.65 nm or another wavelength with a tunable range of 4.83 nm. The super-narrow linewidths of 550 Hz and 600 Hz for two wavelengths are obtained. The proposed EDFL has potential applications in microwave/terahertz-wave generation and high-precision distributed fiber optical sensing.Dual-wavelength single-longitudinal-mode (SLM) erbium-doped fiber lasers (EDFLs) are considered to be excellent sources for applications such as wavelength division multiplexing transmission system, fiber sensing, optical signal processing, LIDAR, and microwave photonic generation [1][2][3][4][5] . The single-/dual-wavelength switchable operation is another crucial target for research of EDFLs [6] .In order to achieve SLM operation for EDFLs, many configurations have been proposed in the past few decades, such as distributed feedback [7,8] , short-cavity distributed Bragg reflector [9] , conventional linear and ring cavities incorporating complicated ultra-narrow-band filters [10][11][12][13] , and compound cavity [14][15][16][17] . Due to the drastic mode competition induced by homogenous gain broadening effect in EDF, stable dual-wavelength SLM oscillation is not easy to achieve. In recent years, many researchers have reported different techniques to demonstrate stable dual-wavelength SLM EDFLs, such as a novel symmetrical fiber Bragg grating (FBG) structure as compact dual-wavelength laser cavity [2] , a reconfigurable dual-pass Mach-Zehnder interferometer (MZI) filter [18] , an unpumped polarization-maintaining EDF saturable absorber filter [19] , two superimposed FBGs and an in-line two-taper MZI filter [20] , a 70 cm long EDF loop attached to a microfiber coupler as wavelength filter [21] , a polarization-maintaining chirped Moiré FBG as ultra-narrow filter [22] , and a special U-bending apparatus based filter [23] . However, all of the techniques cannot achieve continuously tunable wavelength-spacing, switchable single-/dual-wavelength operation and narrow linewidth lasing simultaneously.In this paper, we propose and demonstrate a single-/dualwavelength switchable and tunable SLM EDFL with super-narrow linewidth based on a compound cavity which consists of a ring main cavity and a two-ring subring cavity (TR-SC). The performance of this EDFL is investigated in detail.The configuration of the proposed EDFL is shown in Fig.1. The fiber laser is based on a compound cavity consisting of a main cavity and a TR-SC.
