Fully reconfigurable compact RF photonic filters using high-Q silicon microdisk resonators
(Georgia Institute of Technology, 2011-08)
We present a fully reconfigurable fourth-order RF photonic filter on SOI platform with a tunable 3-dB bandwidth of 0.9–5 GHz, more than 38 dB optical out-of-band rejection, FSR up to 650 GHz, and compact size (total area ...
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 ...
Quantitative modeling of coupling-induced resonance frequency shift in microring resonators
(Georgia Institute of Technology, 2009-12)
We present a detailed study on the behavior of coupling-induced resonance frequency shift (CIFS) in dielectric microring resonators. CIFS is related to the phase responses of the coupling region of the resonator coupling ...
High quality planar silicon nitride microdisk resonators for integrated photonics in the visible wavelength range
(Georgia Institute of Technology, 2009-08)
High quality factor (Q≈3.4×10⁶) microdisk resonators are demonstrated in a Si3N4 on SiO₂ platform at 652–660 nm with integrated in-plane coupling waveguides. Critical coupling to several radial modes is demonstrated using ...
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 ...
