A new method for the calculation of the dispersion of nonperiodic photonic crystal waveguides
(Georgia Institute of Technology, 2004-08)
We present a new method for the calculation of the dispersion diagrams of general nonuniform waveguides. The method is based on the spatial Fourier transform (SFT) of the electromagnetic field distribution along the ...
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 ...
Qualitative demonstration of spectral diversity filtering using spherical beam volume holograms
(Georgia Institute of Technology, 2004-06)
We investigate the feasibility of designing spectral diversity filters using spherical beam volume holograms. Our experimental results qualitatively show the separation of the information of different incident wavelength ...
Investigation of physical mechanisms in coupling photonic crystal waveguiding structures
(Georgia Institute of Technology, 2004-10)
We explain the fundamental physical mechanisms involved in coupling triangular lattice photonic crystal waveguides to conventional dielectric slab waveguides. We show that the two waveguides can be efficiently coupled ...
