  3. 3. Time and Frequency Transfer using Passive Techniques in Active Fiber Optic Networks

    Detta är en avhandling från Stockholm : KTH

    Författare :Sven-Christian Ebenhag; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber link; optical fiber.; Global positioning system GPS ; fiber network; time transfer; two-way; synchronous optical networking SONET synchronous digital hierarchy SDH ; GPS carrier phase;

    Sammanfattning : For the modern society, high precision time and frequency transfer have become crucial since a large number of systems, such as telecommunication systems, require precise and stable synchronization. Electric power companies use synchronized systems for taking stability measurements and searching for errors in their networks. LÄS MER

  4. 4. All-fiber modulators for laser applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mikael Malmström; KTH.; [2012]
    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
