摘要： At least one of two slab waveguides constituting an arrayed waveguide grating is cut and separated together with a substrate on a cross separating face. A slide moving member is arranged over a waveguide forming area formed on the substrate including the separating slab waveguide and a waveguide forming area formed on the substrate including the separating slab waveguide. Temperature dependence of the center wavelength of the arrayed waveguide grating is reduced by slide-moving the separating slab waveguide by the slide moving member along the cross separating face dependently on temperature. The shift of an initial center wavelength is corrected by plastically deforming the slide moving member so that the initial center wavelength is conformed to a grid wavelength.

摘要： An arrayed waveguide grating optical multiplexer/demultiplexer is provided to suppress a temperature depending characteristic of a center wavelength. The arrayed waveguide grating comprises at least one optical input waveguide, a first slab waveguide, an arrayed waveguide, a second slab waveguide, and a plurality of optical output waveguides. The first slab waveguide is separated on an cross separating plane which is intersected to a path of light passing through the first slab waveguide to constitute separated slab waveguides. A slide moving member is provided which may move at least one of these separated slab waveguides along the cross separating plane, depending upon the temperature. A front surface side of the waveguide forming region and a rear surface side of the substrate are sandwiched by a positional shift suppressing member such as a clip. The possition depressing the waveguide forming region by the clip is escaped from the optical axis of the separated slab waveguides.

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.

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 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： The invention provides a simple metallic film manufacturing method for manufacturing an arrayed waveguide grating able to set each light transmitting central wavelength to a set wavelength at optionally predetermined temperature (for example 25° C.). The arrayed waveguide grating is manufactured by using this method. The light transmitting central wavelength of a circuit forming a waveguide forming area on a substrate is measured, and a shift of the light transmitting central wavelength from the set wavelength is corrected by annealing process. A mask has a hole approximately formed in the same shape as the manufactured metallic film, and is arranged such that the hole of the mask corresponds to a manufacturing portion of the metallic film. The metallic film is manufactured by evaporation, etc. A intersecting planes is formed by primary cutting, and a position shifting member is fixed through the metallic film and solder, and a non-intersecting planes is formed by secondary cutting so that the waveguide forming area is cut and separated.
