  • Narrow band fiber Raman optical amplifier
    Patent number: 8773752
    Abstract: Optical Raman fiber amplifier (20), with an amplification fiber, wherein at least one section thereof has a ratio of Raman gain coefficient gR to Brillouin gB gain coefficient of gR/gB larger than 0.001 at the fiber operating temperature and a vacuum wavelength of 1064 nm. The invention further refers to a corresponding light source, the use of a fiber and a method of amplifying light.
    Type: Grant

  • System and method for estimating probabilities of events
    Publication number: 20060193400
    Abstract: A dual adaptive importance-sampling system and method is provided that can estimate the probability of events by combining dual complementary importance-sampling simulations. The present invention exploits the ability to determine an optimal biased pdf using an iterative procedure that requires relatively little a priori knowledge of how to bias. Hence, the present invention is particularly suited for evaluating the BERs and/or WERs of coded communication and storage systems, and is generally applicable to arbitrarily chosen codes. When applied to coded communication and storage systems, the present invention provides a versatile technique for the fast and accurate estimation of BERs and WERs of FEC codes down to values of 10?20 or lower.
