  1. 1. All-fiber modulators for laser applications

    Författare :Mikael Malmström; Fredrik Laurell; Simon Fleming; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; All-fiber; fiber optics; modulation; q-switching; mode-locking;

    Sammanfattning : The objective of this thesis was to explore the usefulness of all-fiber modulators for laser applications. The modulators were all based on refractive index change achieved in the core of the studied fiber- components, exploiting either the elasto-optic effect or the electro-optic effect. LÄS MER
