16QAM silicon-organic hybrid (SOH) modulator operating with 0.6 Vpp and 19 fJ/bit at 112 Gbit/s

We demonstrate a silicon-based 16QAM modulator with a record-low drive voltage of 0.6Vpp and an energy consumption of 19fJ/bit. The device employs silicon slot waveguides with electro-optic organic cladding and enables data transmission at 112Gbit/s.
