    Abstract : A progressive shift from cash and card –based in-store payments, towards contactless mobile payments, is currently in the making on the European market. This shift would imply payments in stores to be performed in a fast, simple, secure and preferably less costly manner, between a consumer´s mobile phone and a merchant´s payment terminal. READ MORE

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

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Miguel Olmedo Iglesias; [2012]
    Keywords : ;

    Abstract : 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. READ MORE
