ABSTRACT:
A self-written branched optical waveguide is formed.A laser beam2from a laser source (not shown) is focused with a lens3onto the face of incidence10of an optical fiber1. The laser beam of an LP11mode was emitted from the face of emergence11, and “bimodal” light intensity peaks were arranged in the horizontal direction (1.A). A slide glass4coated with a photocurable resin gel5was placed horizontally (1.B). A single linear cured material61was formed as the LP11-mode laser beam was emitted from the face of emergence11of the optical fiber1(1.C). A branch portion62was then formed at a distance L from the face of emergence11of the optical fiber1, which was followed by the growth of two cylindrical cured materials63aand63b. The two cylindrical cured materials63aand63bwere linear branches, and formed an angle of about four degrees. An optical waveguide60thus formed was composed of cured materials61, 62, 63a, and63b(1.D).
