Slot waveguide ring resonator modulator
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.
Silicon Polymer Hybrid Slot Waveguide Ring Resonator Modulator 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 .. Silicon-polymer hybrid slot waveguide ring-resonator 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.

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 Using a slot waveguide based electro-optic modulator geometry, we have previously demonstrated ring resonators with substantially better tunability (in Gigahertz per volt) than those built with comparable electrooptic materials in conventional geometries [16].

Integlia, 1 Lianghong Yin, Duo Ding,3 David Z. Pan,3 Douglas M. Gill,4 ... 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. Organic Electro-Optics | Jen Research Group Organic Electro-Optics Introduction. The Jen group’s goal in the research of organic electro-optics is to advance the science and engineering of organic second-order nonlinear optical materials and their hybrid systems, enabling the development of “transformative” electro-optic (EO) technologies for ultrafast information processing.

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 ...
