Optical Characterization and Guided Wave Loss Measurements for End- Capped 6F-Polybenzoxazole
Abstract
A.Mathematica software package to model the behavior of light inside an optical waveguide is discussed. Examples of package features are presented and discussed Possible new waveguide materials are investigated with this package as a baseline for material evaluation. The use of the polymer 6F-PBO-lE as a possible candidate for high temperature optical waveguide material based in its high Tg of 300C and its optical clarity is discussed. Theoretical studies are performed with the Mathematica package. Slab waveguide samples are fabricated by spin-coating on oxidizO5 silicon wafers and characterized through measurements of the index of refraction and waveguide loss. Results show that the material exhibits its lowest loss of 4.5 db/cm at a wavelength of 700nm. We conclude, based on experimental results, that this material, 6F-PBO-1E, while it may be useful for some optical applications, does not meet the Air Force specification of 1 db/cm or less performance guideline for optical waveguide materials and therefore is not appropriate for Air Force applications in its present form.
