Process for inducing or enhancing shear stress-optical properties and reduction or elimination of stress birefringence in optically transmissive materials

摘要

A process for inducing or enhancing shear stress-optical properties and reducing or eliminating stress birefringence in optically transmissive materials is discussed, as well as devices compπsing or incorporating materials subjected to such process Disclosed is an optically transmissive material (figure 5, a fiber optic cable) including a core (10) having an axis and a cladding (11) concentrically disposed about the core (10) wherein the fiber optic cable is modified (via 16) to generate shear stresses in rotational symmetry around the fiber core (10) in a plane orthogonal to the axis.
