In recent decades, much research effort has been invested in the development of photonic integrated circuits, and silicon-on-insulator technology has been established as a reliable platform for highly scalable silicon-based electro-optical modulators. However, the performance of such devices is restricted by the inherent material properties of silicon. An approach to overcoming these deficiencies is to integrate organic materials with exceptionally high optical nonlinearities into a silicon-on-insulator photonic platform. Silicon-organic hybrid photonics has been shown to overcome the drawbacks of silicon-based modulators in terms of operating speed, bandwidth, and energy consumption. This work reviews recent advances in silicon-organic hybrid photonics and covers the latest improvements to single components and device concepts. Special emphasis is given to the in-device performance of novel electro-optical polymers and the use of different electro-optical effects, such as the linear and quadratic electro-optical effect, as well as the electric-field-induced linear electro-optical effect. Finally, the inherent challenges of implementing non-linear optical polymers on a silicon photonic platform are discussed and a perspective for future directions is given.

“…As a consequence, heterogeneous integration of novel materials like electro-optical polymers, [8][9][10][11] ferroelectric materials 12,13 or III-V materials is required. 14 One focus of current research lies on the hybrid-integration of ferroelectric materials like barium titanate (BTO) into silicon-based photonic integrated circuits (PIC), 15 giving rise to an extraordinary Pockels effect. [16][17][18] We present an analysis of a horizontal slot waveguide configuration consisting of barium titanate (BTO) on silicon using a Ba 0.7 Sr 0.3 T iO 3 (BST) layer as template material.…”

In this work, we analyze a horizontal slot waveguide configuration, which evaluates the potential for an integration of barium titanate (BTO) based modulators into a photonic integrated circuit (PIC) technology based on siliconon-insulator (SOI) wafer. The waveguide configuration consists of a doped crystal silicon layer, a Ba 0.7 Sr 0.3 T iO 3 (BST) template layer, a barium titanate (BTO) layer and a doped poly-silicon layer on top. In contrast to current approaches, we analyze the performance of this waveguide-structure by using a vertical electrode configuration that is formed by the doped silicon layer. In this way, the electric field strength is dramatically increased compared to current horizontal electrode configuration.
