Prototype CO₂ laser-induced long-period fiber grating variable optical attenuators and optical tunable filters
(Georgia Institute of Technology, 2004-03)
Prototype devices capable of variable attenuation at a fixed wavelength, wavelength tuning at a constant attenuation, and combinations of these spectral characteristics are demonstrated in CO₂ laser-induced long-period ...
Planar lightwave integrated circuits with embedded actives for board and substrate level optical signal distribution
(Georgia Institute of Technology, 2004-05)
As the data rate of integrated circuits dramatically increases, interconnection speed at the backplane and board levels are beginning to limit system performance, which drives investigations into alternative interconnection ...
Optical and electrical interconnect partition length based on chip-to-chip bandwidth maximization
(Georgia Institute of Technology, 2004-04)
The lengths beyond which board-level optical waveguides are capable of transferring a larger number of bits per second than electrical interconnects are found for various technology generations. As technology scales ...
Photopolymer-based diffractive and MMI waveguide couplers
(Georgia Institute of Technology, 2004-11)
Two-wave-plate compensator method for single-point retardation measurements
(Georgia Institute of Technology, 2004-12)
The two-wave-plate compensator (TWC) technique is introduced for single-point retardation measurements. The TWC method uses a known wave plate together with a wave plate of unknown retardation and produces a linearly ...
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. ...
Optical single-angle plane-wave transmittances/reflectances from Schwarzschild objective variable-angle measurements
(Georgia Institute of Technology, 2004-02)
Photonic crystal structures and other nanoscale and microscale optical structures are centrally important to future device technology. The fundamental infrared single-angle plane-wave experimental characterization of these ...
