Spherical beam volume holograms for spectroscopic applications: modeling and implementation
(Georgia Institute of Technology, 2004-12)
The spherical beam volume hologram, recorded by a plane wave and a spherical beam, is investigated for spectroscopic applications in detail. It is shown that both the diffracted and the transmitted beam can be used for ...
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 ...
Dynamic optical correlation using localized holography
(Georgia Institute of Technology, 2007-03)
A new technique for optical correlation using gated holographic recording is demonstrated. Several persistent holograms are localized within separate slices as close as 33 μm apart along the crystal. Individual holograms ...
Multimodal multiplex spectroscopy using photonic crystals
(Georgia Institute of Technology, 2003-09)
Spatio-spectral transmission patterns induced on low coherence fields by disordered photonic crystals can be used to construct optical spectrometers. Experimental results suggest that 1–10 nm resolution multimodal spectrometers ...
Modeling the propagation of optical beams in three-dimensional photonic crystals
(Georgia Institute of Technology, 2008-05)
We show that the propagation effects of optical beams in three-dimensional photonic crystal structures can be modeled using a direction-dependent effective diffractive index model. The parameters of the model (i.e., the ...
