Slotted waveguides are based on the guiding of light in low refractive index materials and a field enhancement in this particular region of the device. In this letter we experimentally demonstrate electro-optic modulation in slotted photonic crystal waveguides based on silicon-on-insulator substrates covered and infiltrated with nonlinear optical polymers. A photonic crystal heterostructure is used to create a cavity, while simultaneously serving as an electrical connection from the slot to the metal electrodes that carry the modulation signal.en0003-69512009241107American Institut of Physicshttp://doku.b.tu-harburg.de/doku/lic_mit_pod.phpphotonic crystalsilicon-on-insulatorpockels effectelectrooptic effectnonlinear optical polymerJournal Article2010-08-13urn:nbn:de:101:1-20150526175610.15480/882.827Photonischer KristallElektrooptischer EffektPockels-EffektElektrooptische ModulationNLO-PolymereSOI-TechnikElectrooptical effectsNonlinear optical crystals (see also 77.84.-s Dielectric, piezoelectric, and ferroelectric materials)Photonic bandgap materials (for photonic crystal lasers, see 42.55.Tv)Optical processors, correlators, and modulators11420/82910.1063/1.315603310.15480/882.827930768921Journal Article
