![]() The silicon Mach-Zehnder modulator was also analyzed comparatively with a lithium niobate Mach-Zehnder modulator in back-to-back transmission and long-haul transmission, respectively, and verified the negative chirp parameter of the silicon modulator through the experiment. The devices were evaluated through the bit-error-rate characterizations under the system-level analysis. We demonstrate error-free 80km transmission by a silicon carrier-depletion Mach-Zehnder modulator at 10Gbps and the power penalty is as low as 1.15dB. Yi, Huaxiang Long, Qifeng Tan, Wei Li, Li Wang, Xingjun Zhou, Zhiping Both the silicon IQ-MZM and the DD-MZM show potential for optical transmission at metro scale and for data center interconnection.ĭemonstration of low power penalty of silicon Mach-Zehnder modulator in long-haul transmission. We also demonstrate 50 Gb/s (12.5Gbaud) 16-QAM Nyquist-shaped SSB transmission over 320 km SSMF with a BER of 2.7 Ã- 10 -3. Our work is the first experimental comparison between silicon IQ-MZM and silicon DD-MZM in generating SSB signals. The performance difference between IQ-MZM and DD-MZM is most likely due to the non-ideal electrical packaging. Without using any chromatic dispersion compensation, the bit error rates (BERs) of 5.4 Ã- 10 -4 and 9.0 Ã- 10 -5 were measured for the DD-MZM and IQ-MZM, respectively, far below the 7% hard-decision forward error correction threshold. We demonstrate 40 Gb/s (10Gbaud) 16-ary quadrature amplitude modulation (16-QAM) Nyquist-shaped SSB transmission over 160 km standard single mode fiber (SSMF). The impact of electrical packaging on the modulator bandwidth is also analyzed. We have assessed its use for generating Nyquist-shaped single sideband (SSB) signals by operating it either as an IQ Mach-Zehnder modulator (IQ-MZM) or using just a single branch of the dual- drive Mach-Zehnder modulator (DD-MZM). We have designed and fabricated a silicon photonic in-phase-quadrature (IQ) modulator based on a nested dual- drive Mach-Zehnder structure incorporating electrical packaging.
