摘要： An optical waveguide circuit device strong in impact strength in dropping, etc. is provided. A waveguide pattern is formed on a silicon substrate in this optical waveguide circuit device. For example, this waveguide pattern has an optical input waveguide, a first slab waveguide, an arrayed waveguide including a plurality of channel waveguides having lengths different from each other and arranged side by side, a second slab waveguide, and a plurality of optical output waveguides arranged side by side. The first slab waveguide is separated on a cross separating face crossing an optical path passing the first slab waveguide. A temperature dependence in light transmission central wavelength of an arrayed waveguide grating is reduced by sliding and moving a separating slab waveguide side by a slide moving member along the separating face depending on temperature. The cross separating face and a noncross separating face communicated with this cross separating face are set to faces not conformed to a cleavage plane of the substrate.

摘要： An arrayed waveguide grating type optical multiplexer/demultiplexer of the invention eliminates the temperature dependency of the light transmission center wavelengths and suppresses an increase in insertion loss with a simple configuration even under the conditions of high temperature and high humidity. A waveguide forming area comprising an optical input waveguide, a first slab waveguide, an arrayed waveguide formed of a plurality of channel waveguides arranged side by side having a different length each other, and a plurality of optical output waveguides connected one by one is formed on a substrate. For example, the first slab waveguide is separated at crossed separation planes that cross the path of light passing through the first slab waveguide. On the crossed separation planes, a matching grease is applied. A thin film member for covering the area arranged with the matching grease is disposed to suppress the evaporation of the matching grease.

摘要： An arrayed waveguide grating type optical multiplexer/demultiplexer in which a light transmission central wavelength is independent of temperature. A substrate is formed on a waveguide forming region in which optical input waveguides, a first slab waveguide, an arrayed waveguide including a plurality of channel waveguides that are arranged side by side, a second slab waveguide, and a plurality of optical output waveguides arranged side by side are sequentially connected. Dividing lines are set to divide the first slab waveguide into two by intersecting dividing planes that intersect with a route of light traveling along the first slab waveguide. A position shifting member is fixed so as to be secured in a waveguide forming region at its one end and in a waveguide forming region on its other end. The position shifting member fixes to a base the waveguide forming region on the side of a divided slab waveguide and slides the waveguide forming region on the side of another divided slab waveguide. An arrayed waveguide grating is then divided at the dividing lines, separating the first and second waveguide forming regions from each other.
