11. Nonlinearity mitigation in phase-sensitively amplified optical transmission links
Sammanfattning : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifier (EDFA) or any phase-insensitive amplifier is 3 dB. LÄS MER
12. On Filter and Code Design for Energy Efficient 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
13. Impairment Mitigation in High Capacity and Cost-efficient Optical Data Links
Sammanfattning : The work presented in this thesis fits within the broader area of fiber optics communications. This is an important area of research as it provides a breeding ground for the present and future technologies supporting the Internet. LÄS MER

15. Short-range Optical Communications using 4-PAM
Sammanfattning : As the demand for ever higher throughput short-range optical links is growing, research and industry has shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying persists to be the choice for low latency applications, such as high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.
