Abstract

By depositing alternating 1/4 wave layers of silicon nitride and siliconrich silicon nitride at the end of an oplical fiber, it is possible to form a narrow band reflective wave stack. The wavelength of peak reflectivity is a function of temperature. We have been able to measure temperatures in excess of 1,000 centigrade have been measured with an accuracy of less than 1%.
