SpliESR: Tunable Power Splitter Based on an Electro-Optic

Neglecting the radiation losses from waveguide bends, the coupling loss from the Si bus waveguide to the DSHP ring and fabrication-induced roughness, the phase mismatch between the open and closed areas of the DSHP ring resonator is the major reason that leads to the small loaded Q factor. 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 ...

Ultra-high-speed graphene optical modulator design based on tight field ... on tight ﬁeld conﬁnement in a slot waveguide Goran Kovacevic1*, Christopher Phare2, Sze Y. Set1, Michal Lipson2, ... The highest reported bandwidth is 30GHz on a ring resonator structure;15) however, in order to properly utilize graphene in silicon photonic devices the bandwidth should cross the 100GHz mark. 16) There has been no experimental report of a 100GHz graphene modulator; such modulator designs have been mentioned in the literature by Meng et al.,10) where less conservative ... Slot waveguide ring resonators coated by an atomic layer deposited ...

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 ...

is determined for devices fabricated on waveguide ring resonators by measuring the resonator spectral response, and a sharp decrease in resonator quality factor is observed above 70 °C, consistent with switching of VO Double-Slot Hybrid Plasmonic Ring Resonator - mafiadoc.com 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.

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. High speed optical modulator based on silicon slotted-rib ...
