Abstract

An advanced versatile, low-cost polymeric waveguide technology with Bragg gratings has been developed for filter applications in optical communications. Bragg gratings are photochemically formed in single mode polymeric waveguides using holographic techniques. The resulting gratings exhibit excellent filter characteristics; 99.997% reflectivity in a 2 cm grating, which corresponds to refractive index modulation of the order of 10^-3, 0.2 nm width in the reflection peak at the 3 dB point in reflectivity, and no sidelobes in the reflection spectrum. The mechanism of the grating formation is discussed; its understanding enables us to enhance the filter characteristics of the gratings. The impact of temperature and humidity on the filter performance is also presented. The shift of the reflection maximum is 0.23 nm/ degree(s)C. The Bragg shift for a 90% change in relative humidity is 0.2 nm.
