Silicon-organic hybrid (SOH) frequency comb source for data transmission at 784 Gbit/s

We demonstrate a frequency comb generator using silicon-organic hybrid (SOH) electrooptic modulators to obtain flat-top comb spectra. This is the first demonstration of a modulator-based frequency comb generator on silicon. The viability of the device is confirmed in a data transmission experiment achieving an aggregate data rate of 784 Gbit/s.
