Silicon-organic hybrid (SOH) IQ modulator for 16QAM at 112 Gbit/s

摘要

Silicon modulators fabricated by scalable, established CMOS technology, promise an answer to today's power consumption challenges. With advanced modulation formats and the resulting higher spectral efficiencies, long-haul applications for silicon modulators come into reach. Energy efficient, high speed modulators were demonstrated as resonant [1] and non-resonant [2] devices. A single-carrier single-polarization data rate of 56 Gbit/s is considered state-of-the-art [3]. Usually, free-carrier dispersion is exploited in silicon modulators.
