11. Key Signal Processing Technologies for High-speed Passive Optical Networks
Sammanfattning : With emerging technologies such as high-definition video, virtual reality, and cloud computing, bandwidth demand in the access networks is ever-increasing. Passive optical network (PON) has become a promising architecture thanks to its low cost and easy management. LÄS MER
12. Optical Design for Stationary Solar Concentrators
Sammanfattning : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. LÄS MER
13. Parallel computer architectures using optical interconnects
Sammanfattning : .... LÄS MER
14. Design, analysis and simultion for optical access and wide-area networks
Sammanfattning : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. LÄS MER
15. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates
Sammanfattning : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. LÄS MER
