Abstract :
A circuit theory approach is employed to analyze the factors and limitations affecting impedance, optical/electrical velocity matching, and bandwidth in loaded-line traveling-wave modulators. Design improvements are explored that show a potential 30- to 40-percent improvement in bandwidth over previous designs.<>
