Abstract:
A method for manufacturing a lens at an end of an optical fiber, the method comprising:polishing the end while rotating the optical fiber around its axis to form a taper, the rotating including multiple offset axial rotations of the fiber against a polishing medium, the multiple offset axial rotations comprising: contacting the end of the fiber with the polishing medium at a first axial position of the fiber; angularly rotating the fiber about its lengthwise axis a first number of turns to polish the end of the fiber; withdrawing the end of the fiber from contact with the polishing medium; contacting the end of the fiber with the polishing medium at an axial position of the fiber offset from the first axial position; and angularly rotating the end of the fiber about its lengthwise axis to polish the end of the fiber; and fusing a tip.
