A Temperature-Insensitive Third-Order Coupled-Resonator Filter for On-Chip Terabit/s Optical Interconnects
(Georgia Institute of Technology, 2010-12)
We design and demonstrate a temperature-insensitive third-order coupled-resonator filter in the silicon-on-insulator platform for on-chip terabit/s optical interconnects. Optimum filter design enables up to 21 flat-band ...
Single sensor that outputs narrowband multispectral images
(Georgia Institute of Technology, 2010-01)
We report the work of developing a hand-held (or miniaturized), low-cost, stand-alone, real-time-operation, narrow bandwidth multispectral imaging device for the detection of early stage pressure ulcers.
Proximity Lithography in Sub-10 Micron Circuitry for Packaging Substrate
(Georgia Institute of Technology, 2010-11)
Rapid changes in the semiconductor industry will continue toward higher functionality that leads to higher input/outputs (I/O) counts, pushing packaging towards higher density architectures. In the next two to three ...
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 ...
Systematic Design of Wide-Bandwidth Photonic Crystal Waveguide Bends With High Transmission and Low Dispersion
(Georgia Institute of Technology, 2010-06)
We identify factors affecting transmission and dispersive properties of photonic crystal waveguide (PCW) bends, using 2-D simulations and present a method for systematic design of PCW bends to achieve high transmission and ...
Acoustic confinement and waveguiding with a line-defect structure in phononic crystal slabs
(Georgia Institute of Technology, 2010-10)
We present a new way of forming phononic crystal waveguides by coupling a series of line-defect resonators. The dispersion proprieties of these coupled resonator acoustic waveguides CRAW can be engineered by using their ...
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. ...
Absorbing boundary conditions for low group velocity electromagnetic waves in photonic crystals
(Georgia Institute of Technology, 2011-03)
We present an efficient method for the absorption of slow group velocity electromagnetic waves in photonic crystal waveguides (PCWs). We show that adiabatically matching the low group velocity waves to high group velocity ...
On chip complex signal processing devices using coupled phononic crystal slab resonators and waveguides
