Abstract
For high bit rates and long haul optical communication systems using a single-mode fiber, a modulator with low chirp and small size are demanded. An electro-absorption modulator is very attractive because it has some advantages of not only low chirp and small size but also the elimination of polarization control through monolithic integration with a distributed feedback (DFB) laser. The modulation bandwidth of traditional lumped electro-absorption modulators (EAMs) is usually limited by the RC time constant, but the effective resistance R and capacitance C are not easily extracted for advanced device geometries. This paper has presented the important transmission characteristics of EA modulators such as transmission performance efficiency, insertion loss, extinction ratio, , over wide range of the affecting parameters for different selected electro-absorption materials to be the major of interest. Index Terms— GaAs semiconductor ...
