摘要： A fiber collimator is provided, comprising at least two optical components, one of the optical components (e.g., an optical element such as a collimating lens or a plano—plano pellet) having a surface that has a comparatively larger cross-sectional area than the surface of the other optical component(s) (e.g., at least one optical fiber). The optical components are joined together by fusion-splicing, using a laser. A gradient in the index of refraction is provided in at least that portion of the surface of the optical element to which the optical fiber(s) is fusion-spliced or at the tip of the optical fiber. The gradient is either formed prior to or during the fusion-splicing. Back-reflection is minimized, pointing accuracy is improved, and power handling ability is increased.

摘要： A method is provided for fusion-splicing with a laser beam two optical components, one of the optical components (e.g., an optical element such as a lens) having a surface that has a comparatively larger cross-sectional area than a surface of the other optical component (e.g., an optical fiber). The method comprises: (a) aligning the two optical components along one axis; (b) turning on a directional laser heat source to form the laser beam; (c) directing the laser beam to be collinear with that optical component having a smaller cross-sectional area; (d) ensuring that the laser beam strikes the surface of the optical component having the larger cross-sectional area at normal or near normal incidence so that absorption of the laser beam is much more efficient on the surface; (e) adjusting the power level of the laser beam to reach a temperature equal to or higher than the softening temperature of the surface of the optical component having the larger cross-sectional area to form a softening region thereon, thereby achieving the fusion-splicing; and (f) turning off the laser.

摘要： A method is provided for fusion-splicing with a laser beam at least two optical components to a different optical component, the different optical component (e.g., an optical element such as a lens) having a surface that has a comparatively larger cross-sectional area than a surface of the other optical components (e.g., at least two optical fibers). The method comprises: (a) aligning the optical components along an axis; (b) turning on a directional laser heat source to form the laser beam; (c) directing the laser beam to be collinear with those optical components having a smaller cross-sectional area; (d) ensuring that the laser beam strikes the surface of the optical component having the larger cross-sectional area at normal or near normal incidence so that absorption of the laser beam is much more efficient on the surface; (e) adjusting the power level of the laser beam to reach a temperature equal to or higher than the softening temperature of the surface of the optical component having the larger cross-sectional area to form a softening region thereon, thereby achieving the fusion-splicing; and (f) turning off the laser.
