TLDR
Comparisons between modeling and measurement results are made with good agreement obtained for both DC and AC characteristics of Mach-Zehnder silicon optical modulators based on carrier-injection.Abstract:
We present a systematic study of Mach-Zehnder silicon optical modulators based on carrier-injection. Detailed comparisons between modeling and measurement results are made with good agreement obtained for both DC and AC characteristics. A figure of merit, static VπL, as low as 0.24Vmm is achieved. The effect of carrier lifetime variation with doping concentration is explored and found to be important for the modulator characteristics.read more
