Accurate cross-sectional stress profiling of optical fibers
(Georgia Institute of TechnologyOptical Society of America, 2009-09)A novel technique for determining two-dimensional, cross-sectional stress distributions in optical fibers and fiber-based devices is presented. Use of the Brace-Kohler compensator technique and a polarization microscope ... -
Algorithm performance in the determination of the refractive-index profile of optical fibers
(Georgia Institute of TechnologyOptical Society of America, 2008-02)Three algorithms for computing the refractive-index profile of azimuthally symmetric optical fibers via the inverse Abel transform are compared to determine their relative accuracies. Appropriate values of algorithm ... -
Concurrent three-dimensional characterization of the refractive-index and residual-stress distributions in optical fibers
(Georgia Institute of TechnologyOptical Society of America, 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 TechnologyOptical Society of America, 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 ... -
Optical-fiber-to-waveguide coupling using carbon-dioxide-laser-induced long-period fiber gratings
(Georgia Institute of TechnologyOptical Society of America, 2005-08)Optical fibers are expected to play a role in chip-level and board-level optical interconnects because of limitations on the bandwidth and level of integration of electrical interconnects. Therefore, methods are needed to ... -
Polarization-dependent loss and birefringence in long-period fiber gratings
(Georgia Institute of TechnologyOptical Society of America, 2003-12)Widely used descriptions and relationships for birefringence and polarization-dependent loss (PDL), developed primarily for ultraviolet-induced long-period fiber gratings (LPFGs) written in optical fiber, can be invalid ... -
Prototype CO₂ laser-induced long-period fiber grating variable optical attenuators and optical tunable filters
(Georgia Institute of TechnologyOptical Society of America, 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 ... -
Refractive-index profiling of azimuthally asymmetric optical fibers by microinterferometric optical phase tomography
(Georgia Institute of TechnologyOptical Society of America, 2005-05)Accurate nondestructive refractive-index profiling is needed in the modeling, design, and manufacturing of optical fibers and fiber devices. Most profile measurement techniques cannot correctly characterize fibers with ...
