Tuning of resonance-spacing in a traveling-wave resonator device
(Georgia Institute of Technology, 2010-04)
In this work a traveling-wave resonator device is proposed and experimentally demonstrated in silicon-on-insulator platform in which the spacing between its adjacent resonance modes can be tuned. This is achieved through ...
Self-sustained gigahertz electronic oscillations in ultrahigh-Q photonic microresonators
(Georgia Institute of Technology, 2012-05)
We report on theoretical and experimental observations of self-sustained fast [gigahertz (GHz)] electronic oscillations resulting from coupled electron-photon dynamics in ultrahigh-Q Si microdisk resonators with cw pumping. ...
On chip complex signal processing devices using coupled phononic crystal slab resonators and waveguides
(Georgia Institute of Technology, 2012-03)
In this paper, we report the evidence for the possibility of achieving complex signal processing functionalities such as multiplexing/demultiplexing at high frequencies using phononic crystal (PnC) slabs. It is shown that ...
Toward ultimate miniaturization of high Q silicon traveling-wave microresonators
(Georgia Institute of Technology, 2010-09)
High Q traveling-wave resonators (TWR)s are one of the key building block components for VLSI Photonics and photonic integrated circuits (PIC). However, dense VLSI integration requires small footprint resonators. While ...
Systematic design and fabrication of high-Q single-mode pulley-coupled planar silicon nitride microdisk resonators at visible wavelengths
(Georgia Institute of Technology, 2010-02)
High quality (Q ≈ 6 × 10⁵) microdisk resonators are demonstrated in a Si₃N₄ on SiO₂platform at 652–660 nm with integrated in-plane wrap-around coupling waveguides to enable critical coupling to specific microdisk radial ...
Hybrid nanoplasmonic-photonic resonators for efficient coupling of light to single plasmonic nanoresonators
(Georgia Institute of Technology, 2011-10)
We show that efficient coupling of lightwave is possible to an individual plasmonic nanoresonator in a hybrid plasmonic-photonic resonator structure. The proposed hybrid structure consists of a photonic microresonator ...
