Patent attributes
The present invention provides an optical fiber device that takes advantage of the fiber structure to construct mechanically stable devices with components inserted in the optical path. An optical component is inserted in a cavity transversally machined across an optical fiber. The component is secured in the cavity and functionally interrelates with light propagated in the optical fiber. The invention also provides a method for manufacturing an optical fiber device with a component insertion into an optical fiber by machining a cavity in an optical fiber, providing a solid component to be inserted in the optical fiber, positioning the component inside the cavity, and securing the component in the cavity. The component is preferably provided as a glass ribbon and the component is preferably secured in the cavity using laser fusion.
