11. Phase-Sensitive Fiber Optic Parametric Amplifier and Their Applications in Optical Communications
Sammanfattning : This thesis deals with experimental and theoretical aspects of the phase-sensitive fiber optic parametric amplifier (FOPA) and their applications. FOPAs can be oper- ated as both phase-insensitive and phase-sensitive amplifiers (PSAs), with the latter requiring phase-locked input waves, which, until recently, has limited their practi- cal use.

12. Frequency Transfer Techniques and Applications in Fiber Optic Communication Systems
Sammanfattning : Modern society is dependent on communications and the developments of these increases constantly through a seemingly endless demand for communication services and thereby synchronization and time. This is confirmed by a vast range of research on communications, irrespective of technology and protocol. LÄS MER
13. Modeling and Tracking of Stochastic Polarization Drifts in Fiber-Optic Systems
Sammanfattning : In the past decade, accessing information has become easier than ever, leading to a rapid growth in popularity of social media, online gaming, and multimedia broadcast systems. These and other services put pressure on the Internet service providers to support high-speed Internet connections and motivate the need for faster communication systems. LÄS MER
14. On hard-decision forward error correction with application to high-throughput fiber-optic communications
Sammanfattning : The advent of the Internet not only changed the communication methods significantly, but also the life-style of the human beings. The number of Internet users has grown exponentially in the last decade, and the number of users exceeded 3.4 billion in 2016. LÄS MER
15. Implementation of Carrier Phase Recovery Circuits for Optical Communication
Sammanfattning : Fiber-optic links form a vital part of our increasingly connected world, and as the number of Internet users and the network traffic increases, reducing the power dissipation of these links becomes more important. A considerable part of the total link power is dissipated in the digital signal processing (DSP) subsystems, which show a growing complexity as more advanced modulation formats are introduced. LÄS MER
