Abstract
En 中文
We present segmented transmission-line (TML) electroabsorption modulators (EAMs) with characteristic impedance close to 50 M The segmented TML approach allows us to design a traveling-wave EAM with 50 Omega impedance and very high band width. The devices show low return loss (< -15 dB) and excellent frequency response up to 50 GHz, and exhibit a maximum model extrapolated 3 dBe bandwidth (BW) of 9,0 GHz. An effective modeling tool based on Bloch-wave analysis is derived. Design considerations and TML properties for periodic TML-EAMs are discussed.
