Optimization of anisotropically etched silicon surface-relief gratings for substrate-mode optical interconnects
(Georgia Institute of Technology, 2006-01)
The optimum profiles of right-angle-face anisotropically etched silicon surface-relief gratings illuminated at normal incidence for substrate-mode optical interconnects are determined for TE, TM, and random linear (RL) ...
Optimization of sawtooth surface-relief gratings: effects of substrate refractive index and polarization
(Georgia Institute of Technology, 2006-05)
The effect of the refractive index of the substrate together with the incident polarization on the optimization of sawtooth surface-relief gratings (SRGs) is investigated. The global optimum diffraction efficiencies of the ...
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 ...
Attenuation in waveguides on FR-4 boards due to periodic substrate undulations
(Georgia Institute of Technology, 2007-04)
The guided-mode attenuation associated with optical-interconnect-polymer waveguides fabricated on FR-4 printed-circuit boards is quantified. The rigorous transmission-line network approach is used and the FR-4 substrate ...
Optimum parallel-face slanted surface-relief gratings
(Georgia Institute of Technology, 2007-06)
Using a combination of rigorous coupled-wave analysis and simulated annealing, parallel-face slanted surface-relief gratings (PFSSRGs) are optimized. For substrate-mode optical interconnects, profiles are presented for ...
