摘要

Abstract

Energy-efficient electro-optic modulators are at the heart of short-reach optical interconnects

and silicon photonics is considered the leading technology for realizing such devices. However

the performance of all-silicon devices is limited by intrinsic material properties. In particular

the absence of linear electro-optic effects in silicon renders the integration of energy-efficient photonic–electronic interfaces challenging. Silicon–organic hybrid (SOH) integration can overco

me these limitations by combining nanophotonic silicon waveguides with organic cladding materials

thereby offering the prospect of designing optical properties by molecular engineering. In this paper

we demonstrate an SOH Mach–Zehnder modulator with unprecedented efficiency: the 1-mm-long device consumes only 0.7 fJ bit

−1

to generate a 12.5 Gbit s

−1

data stream with a bit-error ratio below the threshold for hard-decision forward-error correction. This power consumption represents the lowest value demonstrated for a non-resonant Mach–Zehnder modulator in any material system. It is enabled by a novel class of organic electro-optic materials that are designed for high chromophore density and enhanced molecular orientation. The device features an electro-optic coefficient of

≈180 pm V

−1

and can be operated at data rates of up to 40 Gbit s
