We report on the design and fabrication of Ge(x)Si(1-x) Mach-Zehnder interferometers based on the thermo-optic effect. The modulators exhibit 8 dB of extinction with a pi-phase-shift power requirement, P(pi), of 245 mW. The 3-dB bandwidth of these thermo-optic devices is 88 kHz. Finally, we present calculations indicating the effect of various parameters on the modulation of the Mach-Zehnder interferometer.
我们报告了基于热光效应的Ge(x)Si(1-x)马赫-曾德尔干涉仪的设计与制造。这些调制器在π相移功率要求P(π)为245 mW时，消光比为8 dB。这些热光器件的3 dB带宽为88 kHz。最后，我们给出了计算结果，表明了各种参数对马赫-曾德尔干涉仪调制的影响。
