High-performance photorefractive polymers sensitized by cadmium selenide nanoparticles
(Georgia Institute of Technology, 2004-07)
We report on efficient and fast hybrid photorefractive polymer sensitized with cadmium selenide (CdSe) quantum dots. The surface of the quantum dots was treated with 4-methylbenzenethiol. This surfactant is responsible for ...
Quasi-free-space optical coupling between diffraction grating couplers fabricated on independent substrates
(Georgia Institute of Technology, 2004-10)
Optical coupling between preferential-order volume diffraction grating couplers fabricated on independent substrates is demonstrated. The coupling efficiency between gratings is quantified as a function of both grating and ...
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. ...
