  • Method for modeling optical fiber amplifiers
    Patent number: 7151631
    Abstract: The present invention provides a method of modeling an optical fiber amplifier, the method being characterized in that it comprises the steps consisting in: establishing (100) the speed equations and the propagation equations of physical phenomena or effects involved in an optical fiber amplifier; obtaining (112) exact analytic solutions for the propagation equations of signals in the fiber, discretizing them, and interpolating them along the fiber; solving (120) the previously discretized speed equations by injecting into them solutions obtained from the propagation equations; and delivering (130) the performance parameters of the fiber in terms of amplification.

  • Injection device for optical fibre and preparation method
    Publication number: 20040047553
    Abstract: The invention concerns an injection device for optical fibre characterised in that it comprises a main fibre (100), and an auxiliary fibre (200) whereof the beveled end (210) is placed on the edge of the main fibre (10), wherein the auxiliary fibre (200) has a numerical aperture smaller than the numerical aperture of the main fibre (100). The invention also concerns a method for preparing the device.
