A hybrid electro-optic polymer and TiO2 double-slot waveguide modulator ... An electro-optic (EO) modulator using a TiO 2 slot hybrid waveguide has been designed and fabricated. Optical mode calculations revealed that the mode was primarily confined within the slots when ... Ultra-high-speed graphene optical modulator design based on tight field ... on tight field confinement in a slot waveguide Goran Kovacevic1*, Christopher Phare2, Sze Y. Set1, Michal Lipson2, ... The highest reported bandwidth is 30GHz on a ring resonator structure;15) however, in order to properly utilize graphene in silicon photonic devices the bandwidth should cross the 100GHz mark. 16) There has been no experimental report of a 100GHz graphene modulator; such modulator designs have been mentioned in the literature by Meng et al.,10) where less conservative ...
Silicon Polymer Hybrid Slot Waveguide Ring Resonator Modulator! SearchMay 21, 2016 - 27 min - Uploaded by andrew mcneilMy first attempt at building the waveguide slot hopefully the first of many as I have a few ideas ..
Active silicon integrated nanophotonics: ferroelectric BaTiO3 ... To exploit the electro-optic effect of the BTO waveguide, we apply the electric field through electrodes patterned in the vicinity of the waveguide. This arrangement allows the waveguide structure to be employed as a modulator by exploiting the electro-optic modulation of the effective refractive index inside the horizontal slot. Optical ring resonators - Wikipedia [citation needed] Furthermore, the refractive index of the waveguide material, the ring resonator material and the medium material in between the waveguide and the ring resonator also affect the optical coupling. The medium material is usually the most important feature under study since it has a great effect on the transmission of the light wave. Parallel-coupled dual racetrack silicon micro- resonators for ...

Periodic waveguide structures for on-chip modulation and sensing
[36, 37] will be investigated in this paper. This modulator consists of racetrack resonator coupled to a bus wavegui de as shown in Fig. 1. The plasmonic slot waveguide with EO organic cladding material is positioned above one of the straight arms (silicon waveguide) of the resonator. This principle is similar to directional coupling between two SpliESR: Tunable Power Splitter Based on an Electro-Optic ... The resonator is made to work in the resonant state whenever we want to filter out the resonant wavelength from the input waveguide. However, when we want to allow the wavelength to pass along the through port, the resonator is brought out of the resonant state by changing its effective refractive index.

Ultrahigh-frequency nano-optomechanical resonators in slot waveguide ring cavities Mo Li,a W. H. P. Pernice, and H. X. Tangb Departments of Electrical Engineering, Yale University, New Haven, Connecticut 06511, USA Label-Free Biosensing With a Slot-Waveguide-Based Ring ... We prove for the first time that surface chemistry for selective label-free sensing of proteins can be applied inside a 100 nm-wide slot region and demonstrate that the application of a slot waveguide instead of a normal waveguide increases the sensitivity of an SOI ring resonator with a factor 3.5 for the detection of proteins.
