Abstract: High performance electro-optic modulator, as the key device of integrated ultra-wideband optical systems, have become the focus of research. Meanwhile, the organic-based hybrid electro-optic modulators, which make full use of the advantages of organic electro-optic (OEO) materials (e.g. high electro-optic coefficient, fast response speed, high bandwidth, easy processing/integration and low cost) have attracted considerable attention. In this paper, we introduce a series of high-performance OEO materials that exhibit good properties in electro-optic activity and thermal stability. In addition, the recent progress of organic-based hybrid electro-optic devices is reviewed, including photonic crystal-organic hybrid (PCOH), silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH) modulators. A high-performance integrated optical platform based on OEO materials is a promising solution for growing high speeds and low power consumption in compact sizes.
