Chromatic dispersion measurement in single-mode optical fibers by acousto-optic modulation and phase detection
A system to measure chromatic dispersion in single-mode optical fibers with near point wavelength resolution is described. Differential propagation constant data for the test fiber is collected by using an acousto-optic modulator to frequency-shift laser light passed to an optical heterodyne. …

Nonlinear Interferometers for Quantum Information Processing and Metrology
… utilize our NLI scheme to perform a precision dispersion measurement as well. First, I developed a comprehensive model, which accounts for the effects of the pump temporal coherence, as well as the chromatic dispersion and the birefringence of the linear medium inside the NLI. I have shown that …

Time domain chromatic dispersion measurements in single mode optical fibers
A time domain chromatic dispersion measurement system for single-mode optical fibers is presented for easy measurements in both the laboratory and the field. This technique uses a relative group delay of a band of light at slightly different wavelengths from a single pulsed laser diode to determine …

Phase and structural changes of nickel catalysts as a function of reaction conditions
… of the Langevin equation as well as by a dispersion measurement, carried out by the titration of the Ni surface with H2. These in situ characterisation techniques showed consistency with the conventional external characterisation techniques and also showed that no size changes occurred …
