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. High-Speed Modulation of a Compact Silicon Ring Resonator In conclusion, we present a high speed ring resonator modulator. The modulation was achieved by carrier depletion in an asymmetric p-n diode structure. The modulator exhibited the DC on/off ratio of 5 dB at - 10V, and a 3dB bandwidth of 19 GHz. This is the fastest reported operation of a silicon ring resonator modulator to date. High speed optical modulator based on silicon slotted-rib ...
Silicon Polymer Hybrid Slot Waveguide Ring Resonator Modulator
The fabricated Mach-Zehnder interferometer (MZI) and ring resonator consist of a Si and TiO2 slot, in which the EO polymer was embedded to realize a low-driving and large bandwidth modulation. The designed optical and electrical constructions are able to provide a highly concentrated TM mode with low propagation loss and effective EO properties. Letter - engineering.purdue.edu gold metal–insulator–metal (MIM) slot waveguide ring coupled to a buried silicon bus waveguide, forming a notch filter with a resonant wavelength of λ res (see section II of the Supplementary Information).

Silicon Polymer Hybrid Slot Waveguide Ring Resonator Modulator
Slot waveguide microring modulator on InP membrane ulators. For the steady state of a ring modulator the high ER is ensured by the (nearly) critical coupling of the ring, which means that the self-coupling coefcient is equal to the round trip transmission coefcient of the ring. The modulation bandwidth can be re-Slot waveguide microring modulator on InP membrane 24 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 ... Ultra-high-speed graphene optical modulator design based ...
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.
