Organic materials combined with strongly-guiding silicon waveguides open the route to
highly efficiently electro-optical devices. Modulators based on the so-called silicon-organic hybrid
(SOH) platform have only recently shown frequency responses up to 100 GHz, high-speed
switching with as little as 60 fJ/bit, and complex data formats. In this article we review the SOH
platform and discuss important devices such as Mach-Zehnder and IQ-modulators based on the
linear electro-optic effect. We further show liquid-crystal phase-shifters with voltage-length
product as low as VπL = 0.06 Vmm and sub-μW power consumption needed for example for
optical switches, filters or device tuning.
