  5. 4. Nonlinear pulse propagation and saturation gain grating phenomena in optical fiber devices

    Författare :Evgeny V. Vanin; KTH; []
    Nyckelord :;

    Sammanfattning : Nonlinear effects are known to influence the propagation ofoptical waves in fibers already at modest power levels. Thisprovides us with a unique tool to observe nonlinear phenomenaunder comparatively simple experimental conditions and alsoopens the door to numerous important applications. LÄS MER
