    Sammanfattning : The majority of today's global Internet traffic is conveyed through optical fibers. The ever-increasing data demands have pushed the optical systems to evolve from using regenerators and direct-direction receivers to a coherent multi-wavelength network. LÄS MER

  5. 19. All-Fiber System for Photonic States Carrying Orbital Angular Momentum : A Platform for Classical and Quantum Information Processing

    Författare :Alvaro Alarcón; Guilherme B. Xavier; Sebastião de Pádua; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quantum Communication; Optical communication; Orbital Angular Momentum; Photonic Lantern; Few-mode-fibers;

    Sammanfattning : The protection of confidential data is a fundamental need in the society in which we live. This task becomes more relevant when observing that every day, data traffic increases exponentially, as well as the number of attacks on the telecommunication infra-structure. LÄS MER

  7. 20. High frequency monoloithic integrated circuits for communication systems

    Författare :Mehran Mokhtari; KTH; []
    Nyckelord :;

    Sammanfattning : The wavelengths of interest in today's communication systemfront-ends are in the same order of magnitude as the availabledevices and circuit sizes. So the wave nature of theinformation can not be neglected. LÄS MER
