Abstract :
A numerical modeling approach based on the microwave transmission (ABCD) matrix theory is developed for analyzing the frequency response of segmented traveling-wave electroabsorption modulators (STEAM). It is found that for 300 μm long exemplary modulation length, the STEAM can provide much wider bandwidth (73 GHz) than the lumped-element (26 GHz) and the continuous traveling-wave (47 GHz) counter-parts, with a small penalty of E/O conversion gain if low-loss passive optical waveguide is available.
