Improved extinction ratio of Mach-Zehnder based optical modulators on CMOS platform
Improved extinction ratio of Mach-Zehnder based optical modulators on CMOS platform
摘要
Abstract
Silicon based optical modulators with improved extinction ratio (ER) of 25 dB were demonstrated on complementary metal oxide semiconductor (CMOS) platform. It was proposed that the effect of optical absorption due to free carriers accumulated in silicon should be considered in the analysis of device configuration. Experimental results presented in this study were identical with the proposed analyses. The modulators were operated with the data transmission rate of 3.2 Gbps.
