“…The presence of residual tensile stresses near the surface of an optical fiber can lead to cracking and a decreased lifetime [16,17]. Crack formation can be reduced, however, if compressive stresses are frozen in near the surface of the fiber [18]. Stress-induced birefringence in optical fibers is detrimental to systems that require low polarization sensitivity [19] or low polarization-mode dispersion [4,[20][21][22].…”

A three-dimensional index-stress distribution (3DISD) measurement method for determining concurrently the refractive-index distributions (RIDs) and residual-stress distributions (RSDs) in optical fibers is presented. The method combines the quantitative-phase microscopy technique, the Brace-Köhler compensator technique, and computed tomography principles. These techniques are implemented on a common apparatus to enable concurrent characterization of the RID and the RSD. Measurements are performed on Corning SMF-28 fiber in an unperturbed section and in a section exposed to CO(2) laser radiation. The concurrent measurements allow for the first accurate comparison of the collocated RID and RSD. The resolutions of the refractive index and stress are estimated to be 2.34×10(-5) and 0.35 MPa, respectively.

Mechanics of Fusion Splicing

Optical Fiber Fusion Splicing

View full text Add to dashboard Cite

At its most basic level, fusion splicing is a mechanical process in which two optical fibers are welded together to form a joint. This welding is accomplished by heating the fiber tips until they attain a temperature at which they soften and coalesce. Mechanical forces, heat transfer, and mass transfer all interact to shape the fusion splice process. An engineering analysis of these phenomena can provide valuable insights into strategies for fabricating low-loss, high strength fusion splices.In this chapter, we will analyze the mechanical aspects of optical fiber fusion splicing beginning with heat transfer in Sect. 3.1. The relevant mechanical forces will be discussed in Sect. 3.2 and the theory of dopant diffusion will be covered in Sect. 3.3. In the concluding section, we will discuss the impact of stress and strain on optical fiber fusion splices.
