    In this work, the strategy, performances and applications of a Raman spectroscopy system with both optical fibre technology and two lasers (red and green) are presented. With this system, we have investigated certain yellow ...
  • Reduction of pulse distortion in travelling wave semiconductor optical amplifiers 

    Soneira Ferrando, M. José; Ruiz Moreno, Sergio (1991)
    Conference report
    Open Access
    The possibility of reducing the gain saturation during the pulse amplification process by means of the compensation of the carrier density variations is investigated. This should be useful in many optical systems and, ...
  • Signal to noise ratio in nonlinear optical amplification process 

    Soneira Ferrando, M. José; Ruiz Moreno, Sergio (1990-01)
    Article
    Open Access
    In this communication, one looks at the influence of the saturation process over the statistical fluctuations (signal to noise ratio) of the optical power at the output of a travelling wave semiconductor optical amplifier ...
