The performance of an EO polymer-based DSHP ring resonator modulator can be calculated by employing a typical high-quality EO polymer with properties as n = 1.5 and r33 = 300 pm/V [32], and assuming 80% of the resonant peak shift is provided by the slot material. Based on the given experimental results, the modulation voltage, V High-speed silicon-organic hybrid modulator enabled by sub ... In this paper, we report a subwavelength grating (SWG) ring resonator based modulator. Compared to slot waveguide, SWG provides competitive mode volume overlap and a comparable propagation loss as strip waveguides. A 3-dB small signal modulation band width of 41.36 GHz has been observed. The ring occupies only an area of 70 Cascaded uncoupled dual-ring modulator - Columbia University time in the dual-ring modulator is reduced, with increased modulation quality. The inter-ring detuning-dependent photon dynamics, Q factor, extinction ratio, and optical modulation amplitude of two cascaded silicon ring resonators are studied and compared with that of a single-ring modulator. Experimentally measured eye diagrams, Compact silicon photonic waveguide modulator based on the ... induced optical modulation of a confined waveguide mode in excess of 6.5 dB at λ = 1550 nm, with 2 dB insertion loss. A 16-fold increase in VO 2 absorption across the phase transition allows the modulator to function as an effective single-pass device that is compact and broadband, in contrast to MZI and resonator-based designs.
A slot-waveguide is an optical waveguide that guides strongly confined light in a subwavelength-scale low refractive index region by total internal reflection. A slot-waveguide consists of two strips or slabs of high-refractive-index (n H ) materials separated by a subwavelength-scale low-refractive-index (n S ) slot region and surrounded by low-refractive-index (n C ) cladding materials.
Periodic waveguide structures for on-chip modulation and sensing hybrid waveguide structures have been proposed to maximize the interaction of photons and polymers, such as slot waveguide,15–18) two-dimensional (2D) slot photonic crystal (PC) waveguide19–21) and one-dimensional (1D) PC wave-guide.22) High modulation efficiency has been reported in slot waveguides because of the strong confinement of optical Ran Ding - Google Scholar Citations Their combined citations are counted only for the first article. ...

High-Q optical resonators in silicon-on-insulator-based slot ... This letter describes the design, fabrication and characterization of high-Q oval resonators based on slot waveguide geometries in thin silicon-on-insulator material. Optical quality factors of up to 27 000 were measured in such filters, and we estimate losses of 210 dB/cm in the slotted waveguides on the basis of our resonator measurements.
