2. 1. Sigma-Delta-over-Fiber for High-Speed Wireless Communication Systems

   Author : Ibrahim Can Sezgin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sigma-delta-over-fiber; Ultra-high speed communication; Distributed-MIMO; Vertical-cavity surface-emitting-laser;

   Abstract : Future mobile communication networks aim to increase the communication speed, provide better reliability and improve the coverage. It needs to achieve all of these enhancements, while the number of users are increasing drastically. READ MORE

4. 2. High-Speed Electroabsorption Modulators and p-i-n Photodiodes

   Author : Robert Lewén; KTH; []
   Keywords : Optical communication; Fiber optic; Electroabsorption modulators; p-i-n photodiodes; transmission line; traveling wave; high-speed; microwave photonics;

   Abstract : This thesis presents methods for optimization ofelectroabsorption modulators (EAM) and p-i-n photodiodes (PD)withrespect to high frequency (HF) performance. Differentreactive matching techniques are investigated such as lumpedmatching and integrated transmission line (TML) layouts includingoperation in the traveling-wave (TW) regime. READ MORE

7. 5. High speed CMOS optical receiver

   Author : Håkan Bengtson; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Optical communication develops very fast and is today the main method for long distance wired communication. However cost is still high. Looking back to the evolution of optical transmission systems, one main objective of system development has become more and more important; minimize cost per gigabytes per second per kilometre, Gb/s/km.
