The novel concept is to combine a photonic crystal heterostructure cavity with a slotted defect waveguide. The photonic crystal lattice can be used as a distributed electrode for the application of a modulation signal. An electrical contact is hence provided while the optical wave is kept isolated from the lossy metal electrodes. Thereby, well known disadvantages of segmented electrode designs such as excessive scattering are avoided. The optical field enhancement in the slotted region increases the nonlinear interaction with an external electric field resulting in an envisaged switching voltage of approximately 1 V at modulation speeds up to 100 GHz.en1094-408720091304313http://doku.b.tu-harburg.de/doku/lic_mit_pod.phpphotonic crystalpockels effectelectrooptic effectnonlinear optical polymeroptical resonatorIngenieurwissenschaftenEngineering and allied operationsJournal Article2010-08-13urn:nbn:de:101:1-20150526176510.15480/882.828Photonischer KristallPockels-EffektNLO-PolymereOptischer ResonatorNonlinear optical crystals (see also 77.84.-s Dielectric, piezoelectric, and ferroelectric materials)Electrooptical effectsPhotonic bandgap materials (for photonic crystal lasers, see 42.55.Tv)Optical processors, correlators, and modulatorsWaveguides, couplers, and arrays (for fiber waveguides, see 42.81.Qb)11420/83010.1364/OE.17.00030410.15480/882.828930768924Other
