Optical Ferrule Assembly and Optical Adhesive Formulation
Abstract:
An optical ferrule assembly includes an optical ferrule including an attachment area, a light input surface and a light output surface; an optical fiber having a fiber end where the light input surface and the fiber end defines a gap therebetween substantially filled with an adhesive, such that light propagating along the optical fiber and having a peak intensity I1≥3 GW/m2, exits the fiber end and enters the optical ferrule through the light input surface after traversing the gap through the adhesive, and exits the optical ferrule through the light output surface. The exiting light has a first beam size, such that after at least 100 hours of aging of the optical ferrule assembly, any change in the first beam size due to a photodegradation of the adhesive is no more than about 10%. The adhesive can be prepared by photocuring an optical adhesive formulation.
