Photorefractive polymer composite operating at the optical communication wavelength of 1550 nm
(Georgia Institute of Technology, 2004-11)
A photorefractive polymer composite sensitized at 1550 nm through direct two-photon absorption has been developed. We show an external diffraction efficiency of 3% in four-wave-mixing experiments and perform holographic ...
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 ...
Wavelength response of waveguide volume grating couplers for optical interconnects
(Georgia Institute of Technology, 2004-09)
The wavelength response of a waveguide volume grating coupler (WVGC) is analyzed for coupling light from a slab waveguide into the superstrate. A leaky-mode approach is used in conjunction with rigorous coupled-wave analysis. ...
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 ...
