- W2989658425 abstract "Methods of design and analysis of radial gradientlenses fabricated by a chemical vapor deposition process aredeveloped. Radial gradient microlenses areuseful for a variety of applications, especially those involvingmicrooptics and coupling light between single-mode optical systems.A methodology for combining commercial lens design software and thecalculation of single-mode coupling efficiency is presented. Thisoffers the ability to analyze completely general optical systemsfor single-mode coupling efficiency. Microoptics manufactured by the modifiedchemical vapor deposition (MCVD) process have refractive indexprofiles that may have perturbations, among them a layer structure.The beam propagation method is used to investigate the effects ofsuch perturbations of the refractive index profile on theperformance of the lenses. A facility wasconstructed in order to perform chemical vapor deposition. Thefacility used a horizontal pulling process in order to produce 0.5mm. diameter lenses from the collapsed preforms. A measurement system based on the refractednear-field method has been designed and built to measure therefractive index profile of samples fabricated by MCVD. Inaddition, a system for measuring the effect of the lenses on aGaussian beam input has also been constructed. These twomeasurements systems are used to confirm effects predicted by thebeam propagation method." @default.
