OPTICAL WAVEGUIDE STRUCTURE BODY, MANUFACTURING METHOD OF THE SAME, MODE SYNCHRONIZATION OPTICAL FIBER LASER APPARATUS, DEPOSITING METHOD OF FINE PARTICLES AND EXTRACTING METHOD OF FINE PARTICLES

摘要

PROBLEM TO BE SOLVED: To easily deposit and arrange fine particles such as carbon nanotube or the like at a necessary place, which is difficult to handle in a conventional method.

SOLUTION: An optical waveguide structure body provided with an optical waveguide, and having an end face which partially includes an exposed part of the optical waveguide is prepared. In a state that the end face is dipped in a medium in which fine particles are dispersed, laser light is emitted from the exposed part of the optical waveguide. Thus the fine particles are selectively deposited at a position which is the exposed part of the optical waveguide and/or the vicinity of the exposed part of the optical waveguide.
