Abstract

We present segmented transmission-line (TML) electroabsorption modulators (EAMs) with characteristic impedance close to 50 Omega. The segmented TML approach allows us to design a traveling-wave EAM with 50 Omega impedance and very high bandwidth. 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 90 GHz. An effective modeling tool based on Bloch-wave analysis is derived. Design considerations and TML properties for periodic TML-EAMs are discussed.
