摘要： A fiber grinding process includes: contacting an end of the optical fiber with a grinding surface in such a manner that a central axis of the optical fiber at the end is inclined to the grinding surface; rotating the optical fiber about the central axis; and changing a contact pressure between the end of the optical fiber and the grinding surface by applying a variable torque while rotating the optical fiber. A substantially cone-shaped end face with a substantially elliptic cross-section may be produced. A fiber grinding apparatus is also disclosed.

摘要： A double-variable-curvature lensed fiber includes a cylindrical fiber body defining a central axis, and a lens body connected integrally to one end of the fiber body. The lens body has first and second inclined curved surfaces disposed respectively at opposite sides of an imaginary plane on which the central axis is disposed, and a light-transmissive portion formed between the first and second inclined curved surfaces. The light-transmissive portion has a first radius of curvature when viewed from a first direction, and a second radius of curvature when viewed from a second direction. The second radius of curvature is different from the first radius of curvature.
