Abstract

Embodiments of an optical adhesive are provided. The optical adhesive includes about 20% to about 60% by volume of first monomers. The first monomers have at least two acrylate or methacrylate groups. The optical adhesive also includes about 40% to about 80% by volume of second monomers. The second monomers have at least one fluorine atom and at least one acrylate or methacrylate group. The optical adhesive has a refractive index of from about 1.40 to about 1.55, and in the temperature range of about 10° C. to about 85° C., the refractive index of the optical adhesive has a thermal drift dn/dT of less than about −4×10/° C. Embodiments of a mechanical joint between two optical fiber segments using the optical adhesive and embodiments of a method for joining two optical fiber segments are also provided.
