摘要
A lensed optical fiber in which a rod-shaped GRIN lens is fused at the tip of an optical fiber is manufactured by executing: a step for fusing together an optical fiber (2) held by a fiber holder (20) and a GRIN lens (3) held by a lens holder (30) with the tips thereof abutting each other; a step for moving the lens holder (30) in the direction away from the fiber holder (20), while relaxing the holding force of the lens holder (30), and reholding the GRIN lens (3); and a step for cutting the GRIN lens (3) with a length equal to the movement distance of the lens holder 30. 展开▼
