Document Type and Number:
Japanese Patent JP3258542
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a branch and confluence optical waveguide which has one main optical waveguide and ≥2 branch waveguides formed on a substrate and makes light branch off and meet together.
SOLUTION: This branch and confluence optical waveguide consisting of the main optical waveguide 1 formed on the substrate, a tapered part 2 which is expanded gradually in width about the center axis of the main optical waveguide 1, and a group of optical waveguides (two branch waveguides 3 and 4) which are arranged opposite the tapered part 2 and as wide as each other has a shift of a specific interval (δX) between the center axis of the whole optical waveguide group and the center axis of the main optical waveguide.
