Two-wave-plate compensator method for full-field retardation measurements
(Georgia Institute of Technology, 2006-01)
The two-wave-plate compensator (TWC) method is expanded for full-field retardation measurements by use of a polarization microscope. The sample image is projected onto a CCD camera connected to a computer, allowing the ...
Concurrent three-dimensional characterization of the refractive-index and residual-stress distributions in optical fibers
(Georgia Institute of Technology, 2012-08)
A three-dimensional index-stress distribution (3DISD) measurement method for determining concurrently the refractive-index distributions (RIDs) and residual-stress distributions (RSDs) in optical fibers is presented. The ...
Microinterferometric optical phase tomography for measuring small, asymmetric refractive-index differences in the profiles of optical fibers and fiber devices
(Georgia Institute of Technology, 2005-01)
A new technique, microinterferometric optical phase tomography, is introduced for use in measuring small, asymmetric refractive-index differences in the profiles of optical fibers and fiber devices. The method combines ...
Pattern-integrated interference lithography: single-exposure fabrication of photonic-crystal structures
(Georgia Institute of Technology, 2012-06)
Multibeam interference represents an approach for producing one-, two-, and three-dimensional periodic optical-intensity distributions with submicrometer features and periodicities. Accordingly, interference lithography ...
Conditions for primitive-lattice-vector-direction equal contrasts in four-beam-interference lithography
(Georgia Institute of Technology, 2009-08)
Four distinct conditions for primitive-lattice-vector-direction equal contrasts in four-beam interference are introduced and described. By maximizing the absolute contrast subject to an equal contrast condition, lithographically ...
Three-beam-interference lithography: contrast and crystallography
(Georgia Institute of Technology, 2008-06)
Specific configurations of three linearly polarized, monochromatic plane waves have previously been shown to be capable of producing interference patterns exhibiting symmetry inherent in 5 of the 17 plane groups. Starting ...
