  We introduce electrically-poled small molecule assemblies that can serve as
the active electro-optic material in nano-scale guided-wave circuits such as
those of the silicon photonics platform. These monolithic organic materials can
be vacuum-deposited to homogeneously fill nanometer-size integrated-optics
structures, and electrically poled at higher temperatures to impart an
orientational non-centrosymmetric order that remains stable at room
temperature. An initial demonstration using the DDMEBT molecule and corona
poling delivered a material with the required high optical quality, an
effective glass transition temperature of the order of $\sim 80$ $^\circ$C, and
an electro-optic coefficient of $20$~pm/V.
