MCF COUPLING DEVICE AND MCF COUPLING METHOD
This abstract first appeared for US patent application 20250085479 titled 'MCF COUPLING DEVICE AND MCF COUPLING METHOD
Original Abstract Submitted
an mcf coupling device includes: a first mcf, a second mcf, and a third mcf, each of mcfs including cores; a first optical collimator that converts light output from cores included in the first mcf individually into collimated light and generates a group of light beams constituted of the collimated light; a first optical splitter that splits at least a part of the group of light beams, at a predetermined split ratio, in a first direction and in a second direction; a second optical collimator that couples each of beams of collimated light contained in the group of light beams being output in the first direction individually into cores in the second mcf; and a third optical collimator that couples each of beams of collimated light contained in the group of light beams being output in the second direction individually into cores in the third mcf.
