Title: Preparation of tapered optical waveguide
Inventor: YAMAMOTO KAZUHISA
IPC: G02B6/30
Filed: 1985-02-19
Abstract: PURPOSE:To obtain high efficiency in coupling by combining a stage for forming a light incident section by lowering the level of ion exchanging soln. by evaporation with a stage for forming an optical waveguide section by dipping whole surface of a substrate in the ion exchange soln. CONSTITUTION:For example, a section to be cleared 3 where Al film is not deposited forms an optical waveguide by being ion exchanged. When a light incident section 4 is dipped in benzoic acid soln. 5, the liquid level 6 is lowered by the evaporation of the soln. 5 causing change of refractive index in each part of the light incident section 4. The liquid level 6 is lowered during the ion exchange. When whole body of an LiNbO3 substrate 1 is dipped in the benzoic acid soln. 5 to execute ion exchange, the refractive index of an optical waveguide 3' formed on the LiNbO3 substrate 1 increases by the ion exchange and the depth is increased. The coupling efficiency is remarkably improved by forming such light incident section.
