Latest Patents

Kenji Fujino holds a patent for a method titled "Etching an optical fiber fusion splice." This patent describes a process where an exposed part of at least one of two optical fibers, which have different mode field distributions, is heated by a burner. This heating allows for a continuous variation of the mode field distribution along the length of the optical fiber. The exposed end of at least one of the optical fibers is then cleaved to ensure that the mode field distributions at the splice end faces of the two fibers are substantially coincident. This method results in low splice loss, which is crucial for maintaining signal integrity in optical communications. Following the fusion splicing, the heated portion of the optical fiber undergoes a surface treatment using a hydrofluoric acid solution to prevent deterioration of its mechanical strength.
