    Abstract: PROBLEM TO BE SOLVED: To provide a mode conversion device that is configured to facilitate efficient coupling of optical signals passing between an optical part having a different mode field from the device and/or another waveguide. SOLUTION: The device for altering the mode field of the optical signals includes: a pigtail fiber 22; a GRIN fiber lens 24 which is directly splice-joined to one end of the pigtail fiber 22 and has a larger outer diameter than that of the pigtail fiber 22; and a reflection surface 26 which is arranged to one end of the GRIN fiber lens 24. An additional reflection element 36 may be arranged on the reflection surface 26 by fixing or other methods. An optical beam path 38 is emitted from the core 40 of the pigtail fiber 22 and is re-orientation toward a curved surface 34 at the reflection surface 26. The curved surface 34 forms a conic surface, condenses beams along one axis and functions as a cylindrical lens in order to avoid condensation along the other axis. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: A spherical lens formed by fusing a generally homogenous glass lens blank to the distal end of an optical fiber, heating and tensioning the lens blank to separate it in two segments with the segment attached to the optical fiber defining a tapered end, and heating the lens blank above its softening point so that the spherical lens forms. The lens blank is fabricated from a 4 weight percent borosilicate glass having a softening point less than that of the core of the optical fiber. The lens member defines a throat region adjacent the optical fiber whose cross-sectional dimension is substantially greater than the diameter of the optical fiber, but substantially less than the diameter of the spherical lens.

    Abstract: An apparatus for altering the mode field of an optical signal is disclosed. The apparatus includes a GRIN-fiber lens and a reflective surface disposed at one end of the GRIN-fiber lens, the reflective surface configured to cooperate with the GRIN-fiber lens to redirect the path of the optical signal directed against the reflective surface. A method of manufacturing an apparatus for altering the mode field of an optical signal and an optical assembly are also disclosed.

    Abstract: A fiber lens includes a graded-index lens, a single-mode fiber disposed at a first end of the graded-index lens, and a refractive lens having a hyperbolic or near-hyperbolic shape disposed at a second end of the graded-index lens to focus a beam from the single-mode fiber to a diffraction-limited spot.
