Enhanced temperature sensing with liquid-crystal filling - SPIE Micro-ring resonators based on such double-slot waveguides have been shown to tolerate larger fabrication errors than their single-slot counterparts. 3 Moreover, sensitivity can be enhanced by filling the waveguide slot with a substance whose refractive index is responsive to the parameter being measured. SpliESR: Tunable Power Splitter Based on an Electro-Optic Slotted Ring ... The silicon strip waveguide ring resonator of radius 50 ... In our design of the electro-optic slotted ring resonator, we varied the slot width from 80 nm to 220 nm in order to determine the optimal values of the slot width in terms of the overlap factor and the optical loss. We calculated both the variation in the overlap factor and in the optical loss with a change in slot width, as shown in Fig. 3. It can be observed from Fig. 3 that with an increase in the slot width, there is a decrease ... Periodic waveguide structures for on-chip modulation and sensing The SWG waveguide ring resonator has a bulk sensitivity more than 400nm/RIU, which is much higher than its strip waveguide counterpart. Furthermore, its surface sensitivity is relatively independent of the thickness of analytes accumulated on its surface. Towards a millivolt optical modulator with nano-slot waveguides
Optical Peaking Enhancement in High-Speed Ring Modulators
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. 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. 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.
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.
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

Silicon waveguides and ring resonators at 5.5 m struct high-Q ring resonators. Ring resonators in the NIR have had a number of applications, including biosensing,8 modulation,9 and wavelength conversion.10 Here we show SOS based waveguides and the first ring resonators at wave-lengths between 5.4–5.6 m. We demonstrate a waveguide loss of 4.0 0.7 dB/cm and a ring resonator Q-value of 3.0 k. Plate-slot polymer waveguide modulator on silicon-on 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. 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.
