High-Speed Silicon-Organic Hybrid (SOH) Modulator with 1.6 fJ/bit and 180 pm/V In-Device Nonlinearity

We report on a 40 Gbit/s silicon-organic hybrid (SOH) modulator with 11 dB extinction ratio. A novel electro-optic chromophore with record in-device nonlinearity of 180 pm/V leads to VπL = 0.5 Vmm and a low energy consumption of 1.6 fJ/bit at 12.5 Gbit/s.
