| Title: | Studies on strain and temperature characteristics of a slanted multimode fiber Bragg grating and its application in multiwavelength fiber Raman ring laser | Authors: | Zhao, CL Li, Z Demokan, S Yang, X Jin, W Lu, C |
Issue Date: | Jun-2006 | Source: | Journal of lightwave technology, June 2006, v. 24, no. 6, p.2394-2400 | Abstract: | Detailed strain and temperature characteristics of a 2°slanted multimode fiber Bragg grating (MFBG) are developed theoretically and observed experimentally. Results show that the strain and temperature sensitivities are almost the same for different transmission dips of the 2°slanted MFBG. Utilizing two characteristics of the 2°slanted MFBG, namely 1) resonant wavelength intensities strongly affected by excited mode propagating before the grating and 2) uniform strain sensitivities of different resonant wavelengths, a switchable and tunable multiwavelength fiber Raman ring laser is realized. The configuration is simple and multipurpose. Results show that the laser can generate single-, dual-, three-, four-, and five-wavelength lasing by switching between each operation if a mode scrambler (MS) that is inserted in front of the slanted MFBG is adjusted; furthermore, a 4.2-nm continuous wavelength-tuning range is achieved by straining the slanted MFBG when the MS is fixed. | Keywords: | Fiber Raman laser Multiwavelength fiber laser Slanted multimode fiber Bragg gratings (MFBGs) Wavelength switching Wavelength tuning |
