| Summary: | Optical communication systems are expanding from the conventional point‐to‐point system to the mesh‐type network systems for subscribers. As a result, the requirement for passive circuits such as optical divider, optical combiner, and optical switch is increased. Since optical waveguide‐type circuits have superior stability and mass producibility, they are considered important for construction of future optical communication systems.
This paper describes development of the planar lightwave circuit (PLC) technology using the silica‐based waveguide on a silicon substrate. In the first half, the design technology of the silica‐based waveguide, the design and production examples of PLCs, and the system experiment examples are introduced. In the latter half, the latest tendency of high‐density integrated PLCs is emphasized based on the use of the high relative refractive index difference (high‐Δ) with a view to large‐scale PLC, and the characteristics of the high‐Δ waveguide and examples of its applications to high‐density integrated optical circuits are presented. |
