  1. 1. Design, Fabrication and Analysis of InP-InGaAsP Traveling-Wave Electro-Absorption Modulators

    Författare :Stefan Irmscher; KTH; []
    Nyckelord :fiber-optic communication; modulator; electroabsorption; traveling-wave; InP; broad-band modulation;

    Sammanfattning : External modulators will become key components in fiberoptical communica- tion systems operating at 40Gbit/s andhigher bitrates. Semiconductor electro- absorption (EA)modulators are promising candidates because of their high-speed potential, and their process compatibility with thecorresponding semi- conductor laser light sources.

  7. 5. 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
