Enhanced S-band Brillouin Erbium Fiber Laser with Additional Edfa
A short wavelength band Brillouin Erbium Fiber Laser (S-band BEFL) with enhanced characteristics using an additional erbium-doped fiber amplifier (EDFA) in the sub-loop of the BEFL system. Compared with the conventional BEFL without the additional EDFA, the enhanced BEFL has improved the number of channels as well as the flatness of the Brillouin Stoke’s peak power. By incorporating a double-pa...
متن کاملOptimization of output coupling ratio on the performance of a ring-cavity Brillouin-erbium fiber laser.
The operation of a single-wavelength Brillouin-erbium fiber laser (BEFL) system with a Brillouin pump preamplified technique for different output coupling ratios in a ring cavity is experimentally demonstrated. The characteristics of Brillouin Stokes power and tunability were investigated in this research. The efficiency of the BEFL operation was obtained at an optimum output coupling ratio of ...
متن کاملHigh Gain Erbium Doped Fiber Amplifiers
Performance improvements by using an isolator as an amplified spontaneous emission suppressing component within erbium-doped fibers are evaluated. Simultaneous high-gain and near-quantum-limited noise figures can be obtained by such a scheme. The noise figure improves for input signal powers below -5 dBm and an improvement of 2.0 db with a simultaneous gain increase of 4.1 dB is measured relati...
متن کاملTunable range enhancement of Brillouin-erbium fiber laser utilizing Brillouin pump pre-amplification technique.
We demonstrate an enhanced multiwavelength L-band Brillouin-erbium fiber laser (BEFL), in which the Brillouin pump is pre-amplified before entering the single-mode fiber. The Brillouin pump pre-amplification provided by the Erbium-doped fiber has created higher intensity of Brillouin Stokes line generated in the single-mode fiber that leads to the homogenous gain saturation. Thus the built-up o...
متن کاملBrillouin signal amplification in pumped erbium-doped optical fiber
Amplification of Brillouin scattering signal extends the measurement range and improves the signal-to-noise ratio of fiber-optic distributed Brillouin sensors. Here, we investigate the amplification effect of a 980-nm pump laser on Brillouin gain spectrum in an erbium-doped optical fiber. The Brillouin-scattered Stokes power increased exponentially with increasing pump power, exhibiting approxi...
