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. Coupled-ring-resonator-based silicon modulator for ... modulation speed. Coupled-ring-resonator structures composed of a sequence of micro-resonators coupled to an optical waveguide have been reported [8, 9]. Previously, these structures are used for slow light or nonlinear optics. In this paper, we propose and analyze a coupled-ring-resonator-based modulator, in which Optical Peaking Enhancement in High-Speed Ring Modulators Gould M. et al.

We demonstrate a ring-resonator modulator based on a silicon-polymer hybrid slot waveguide with a tunability of 12.7 pm/V at RF speeds and a bandwidth of 1 GHz, for optical wavelengths near 1550 nm. Our slot waveguides were fabricated with 193 nm optical lithography, as opposed to the electron beam Silicon-polymer hybrid slot waveguide ring-resonator modulator ...

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.

OSA | 50-Gb/s ring-resonator-based silicon modulator We achieved 50-Gb/s operation of a ring-resonator-based silicon modulator for the first time. The pin-diode phase shifter, which consists of a side-wall-grating waveguide, was loaded into the ring resonator. The forward-biased operation mode was applied, which exhibited a VπL as small as 0.28 V·cm at 25 GHz. The driving voltage and optical insertion loss at 50-Gb/s were 1.96 Vpp and 5.2 dB ...

Slot-waveguide - Wikipedia 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.

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

An optical ring resonator is a set of waveguides in which at least one is a closed loop coupled to some sort of light input and output. (These can be, but are not limited to being, waveguides.) The concepts behind optical ring resonators are the same as those behind whispering galleries except that they use light and obey the properties behind constructive interference and total internal
