Abstract

A method of coupling a high-power optical signal between an optical fiber and a mating optical component, the optical signal ranging in wavelength from x to y, and having a first diameter while propagating in a mode field within the fiber, the method comprising: (a) converting the high-power optical signal between the first diameter in the fiber and a second diameter significantly greater than the first diameter using a GRIN lens fused to an end of the fiber, the GRIN lens having a diameter substantially the same as that of the optical fiber and a length l complying with the following equation:¼x+½nx≦l≦¼y+½ny,
