    Sammanfattning : Segmented traveling wave electro-absorption modulators (TWEAMs) can provide a modulation speed above 100 Gb/s, which is needed in new optical communication networks. In the EU-project TWILIGHT, KTH continues the design work of TWEAMs in the EU-projects IPHOBAC and HECTO with the aim to design a new optical modulator to be integrated with an electronic layer.

  5. 4. Investigation of the chirp properties of DFB-EAM’s for high speed baseband and RoF transmission links

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Miguel Olmedo Iglesias; [2012]
    Nyckelord :;

    Sammanfattning : The ever increasing bandwidth demands driven by an explosion in the mobile device market calls for more and more optical and wireless convergence due to the ability of optical communication systems to transport larger amounts of information to longer distances. Optical modulators are in charge of performing the electrical-to-optical domain conversion, which place them as one of the critical components in optical communication systems. LÄS MER

  7. 5. Simulation of Traveling Wave Electroabsorption Modulators Suitable for 100Gbps

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Akinwumi Abimbola Amusan; [2011]
