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 ...
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 ...
Planar photonic crystal microspectrometers in silicon-nitride for the visible range
(Georgia Institute of Technology, 2009-09)
We demonstrate the feasibility of forming a compact integrated photonic spectrometer for operation in the visible wavelength range using the dispersive properties of a planar photonic crystal structure fabricated in silicon ...
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 ...
Strong angular dispersion using higher bands of planar silicon photonic crystals
(Georgia Institute of Technology, 2008-09)
We present experimental evidence for strong angular dispersion in a planar photonic crystal (PC) structure by properly engineering the modes in the second PC band. We show that by using the second photonic band of a square ...
