Abstract

Among several possible failure modes in a Fiber Bragg Grating (FBG) device, fracture of the optical fiber is one of great importance. Reliability of fiber in such a device has to be ascertained and assured. A technique to evaluate the fiber strength in this device has been developed, and the extent of degradation due to processing and handling has been established. The impact of mechanical failures in other parts of the device on fiber failure is also addressed and evaluated. The failure mechanisms and its implications on fiber reliability are discussed. A proof stress level has been determined and implemented in the fabrication to assure mechanical reliability of the fiber against time. Based on the fiber strength distribution, proof stress level used, and the applied stress, a FIT rate is calculated using power law crack growth model for silica fibers. This study estimates an average FIT of 0.06 at ambient room temperature over a 25 year life for fiber failure in FBG devices fabricated by Corning Inc.
