Abstract

A microring-based silicon modulator operating at 40 Gb/s near 1310 nm is demonstrated for the first time to our knowledge. NRZ-OOK signals at 40 Gb/s with 6.2 dB extinction ratio are observed by applying a 4.8 Vpp driving voltage and biasing the modulator at 7 dB insertion loss point. The energy efficiency is 115 fJ/bit. The transmission performance of 40 Gb/s NRZ-OOK through 40 km of standard single mode fiber without dispersion compensation is also investigated. We show that the link suffers negligible dispersion penalty. This makes the modulator a potential candidate for metro network applications.

摘要

据我们所知，首次展示了一种基于微环的硅调制器，其在1310nm附近以40 Gb/s的速率运行。通过施加4.8 Vpp的驱动电压并将调制器偏置在7 dB插入损耗点，观察到了消光比为6.2 dB的40 Gb/s非归零开关键控（NRZ-OOK）信号。能量效率为115 fJ/bit。还研究了40 Gb/s NRZ-OOK信号在40 km标准单模光纤中无色散补偿的传输性能。我们表明，该链路的色散代价可忽略不计。这使得该调制器成为城域网应用的潜在候选者。
