  1. 1. High-Speed Electroabsorption Modulators and p-i-n Photodiodes

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.
