Hybrid SOI nonlinear optical polymer racetrack resonator designs for electro-optical modulation — •Jan Hampe, Jan-Hendrik Wülbern, Stefan Prorok, Alexander Petrov, and Manfred Eich — TU Hamburg-Harburg, Eißendorfer Str. 38, 21073 Hamburg

Racetrack resonators based on the silicon-on-insulator (SOI) platform are proposed for modulation of an optical continuous wave (CW) signal by electrical signals.

The resonators are functionalized by a cladding of a second order nonlinear optical (NLO) polymer.

Two different concepts for the racetrack design employing different waveguide geometries for quasi-TE and quasi-TM polarization operation are presented.

The Pockel's coefficients of the in device poled NLO polymers are determined by the shift of the resonance wavelength with applied voltage and the modulation depth with low frequency signals.

In both resonator designs the electrical contact is established by fully etched segmented electrode sections to allow for an easy fabrication process.
