| 英文摘要 | PURPOSE:To easily control a branching ratio and the coupling efficiency by improving the uniformity of working depth and the accuracy of a working position at the time of wave front dividing type coupler formation. CONSTITUTION:The integrated type optical coupler 2 for the coupling of light is formed in a channel optical waveguide structure 1 which has a ridge structure, etc. The node of the leakage of the field distribution of the lateral light of the optical waveguide, i.e., flat part 3 is formed at the formation place of the coupler to be a slit 2 and wave front division type branching and coupling are performed. |
