PROBLEM TO BE SOLVED: To provide a digital optical switch which is operative with low voltage. SOLUTION: A single mode optical waveguide 12 is formed on a Z-cut LiNbO3 substrate 11 by diffusing Ti on the substrate 11. This single mode optical waveguide 12 is branched to two pieces of arm waveguides...
