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 ...
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 ...
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 ...
Preconditioned superprism-based photonic crystal demultiplexers: analysis and design
(Georgia Institute of Technology, 2006-11)
We present the analysis and design of a new type of photonic crystal (PC) demultiplexers (i.e., preconditioned demultiplexer), in which the simultaneous existence of the superprism effect and the negative effective index ...
Compact wavelength demultiplexing using focusing negative index photonic crystal superprisms
(Georgia Institute of Technology, 2006-03)
Here, we demonstrate a compact photonic crystal wavelength demultiplexing device based on a diffraction compensation scheme with two orders of magnitude performance improvement over the conventional superprism structures ...
