“….64 W at 1119.152 nm, corresponding to optical efficiency of 32% and 36%, respectively. It can be found that each largest power is above half of that of the dual-wavelength operation, and the result aligns with the discussions in reference [8]. No matter in dual-or single-wavelength operation, the power of the line at 1119.152 nm is a little higher than that at 1118.912 nm.…”

A single-and dual-wavelength switchable polarized Yb-doped double-clad fiber laser around 1120 nm based on a pair of fiber Bragg gratings (FBGs) is demonstrated. The polarization-maintaining (PM) linear cavity is composed of a double clad PM Yb-doped fiber (YDF) and a pair of PM FBGs. The laser can operate in stable dual-wavelength or wavelength-switching modes due to the polarization hole burning (PHB) and the spatial hole burning (SHB) enhanced by the PM linear cavity. In dual-wavelength operation, the two orthogonally polarized wavelengths are centered at 1118.912 nm and 1119.152 nm, with an interval of 0.24 nm and a signal to noise ratio (SNR) of 35 dB. The maximum output power is 14.67 W when the launched LD pump is 24 W corresponding to an optical efficiency of 61.1%. The lasing lines switchover may be realized by adjusting the polarization controller (PC) fitted in the cavity. The two single-wavelengths are 1118.912 nm and 1119.152 nm. When the injected LD pump is 24 W, the highest output powers are 7.68 W and 8.64 W corresponding to optical efficiencies of 32% and 36% respectively. The spectral linewidth of the lasing lines are 0.075 nm and 0.07 nm, and the average numerical values of PER are 20.3 dB and 19.9 dB, respectively.

 Abstract-We propose and experimentally demonstrate a compact all-fiber 2D location sensor suitable for 12-key keyboard application. The proposed sensor consists of two groups of fiber bragg gratings (FBGs) one of which is spatially arranged in 4×3 array. Strain-induced Bragg wavelength shifts finely adjust the stopband of incident light by pressing the crossing points of the grating array, leading to corresponding reflections from the reference group due to the one-to-one correspondence between two groups. This sensor has the features of being flexible, low insertion loss, simple structure and also combines with the advantages of the FBG-based sensors with high sensitivity and accuracy. Index Terms-2D location sensor, FBG array, fiber keyboard

“…Another approach is a long-length ring cavity to offer higher output power without special requirements for the gain media [6]. However, since a fiber ring laser usually has a long cavity with closely spaced longitudinal modes, an ultranarrow bandpass filter (BPF) must be incorporated to eliminate multilongitudinal-mode oscillation and mode hopping [7]. Cusano et al produce a tapered region in a fiber Bragg grating (FBG) by the arc discharge technique [8].…”

A novel linear cavity erbium-doped fiber (EDF) laser based on a structured chirped fiber Bragg grating (CFBG) filter is proposed for stable single-polarization (SP) single-longitudinal-mode (SLM) operation. For the first time, to the best of our knowledge, a structured CFBG filter with an ultranarrow transmission band which is generated by tapering directly on CFBG is used to select the laser longitudinal mode. The SLM operation is obtained by using the structured CFBG together with an unpumped EDF acting as a saturable absorber. The fluctuations of the laser peak power and center wavelength are less than 0.07 dB and 1 pm in 1 h, respectively. The stable SP operation is achieved by using the inline broadband polarizer. The measured 20 dB laser linewidth is about 27.7 kHz, which indicates the laser linewidth is approximately 1.39 kHz FWHM.
