Abstract
This paper presents the large signal modeling and simulation of two segmented travelling wave electroabsorption modulators (TWEAM) as a cascaded TWEAM (CTWEAM) structure. It will be demonstrated that a mushroom shaped mesa structure with low series resistance (0.69Ω-mm) will have 3dB bandwidth more than sufficient for 100Gbps operation. For a CTWEAM device with 990μm active segment length, 1.1V bias voltage and only 0.4V peak-to-peak (Vp–p) modulating voltage has a bandwidth of 110GHz, extinction ratio >4dB and flat frequency response. This device would be an attractive candidate for short distance optical fiber communication as well as long distance telecommunication at 0.4Vp–p and 1Vp–p input RF signal, respectively.
