| Abstract: | A simple and cost-effective wavelength-switchable fiber ring laser based on a chirped moire fiber grating (CMFG)and an erbium-doped fiber amplifier (EDFA) is proposed,and stable wavelength Iasing oscillations at room temperature iS experimentally demonstrated.To serve as a wavelength selective element,the CMFG possesses excellent comb-like filtering characteristics including stable wavelength interval and ultra-narrow passband.and its fabrication method iS easy and flexible.The measured optical signal-to-noise ratio reaches the highest value of 50 dB and the power fluctuation of each channel output iS less than 0.5 dB within an hour.The output laser power of different channels is almost identical(difference of less than 1 dB) within the tunable range.Methods to optimize the laser performance are also discussed and the superiority of the CMFG iS experimentally demonstrated. |
