摘要： An arrayed waveguide grating including at least one first optical waveguide, a first slab waveguide, a plurality of arrayed waveguides, a second slab waveguide, and a plurality of second optical waveguides. The plurality of arrayed waveguides are connected to the at least one first optical waveguide via the first slab waveguide. Each of the plurality of arrayed waveguides has a different length. The plurality of second optical waveguides are connected to the plurality of arrayed waveguides via the second slab waveguide. At least one of the first and second slab waveguides is partitioned to first and second segments at a partition surface intersecting a path of light which travels through the arrayed waveguide grating. At least one of the first and second segments is configured to be slid along the partition surface to compensate an optical transmitting center wavelength of the light according to a temperature of the arrayed waveguide grating.

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： The invention relates to a small-sized multiple-core optical connector having high reliability, which can be easily assembled and manufactured. A plurality of array guide grooves (22) are arrayed and formed on a flat substrate (21). The array pitch interval of the array guide grooves is roughly coincident with the outer diameter of bare optical fibers (4a), (4b). The first optical fiber tape (6a) and the second optical fiber tape (6b) are disposed at the rear end side of the flat substrate (21) so as to overlap each other, wherein the first bare optical fibers (4a) of the first optical fiber tape (6a) and the second bare optical fibers (4b) of the second optical fiber tape (6b) are alternately array-converted and accommodated in the array guide grooves (22). The bare optical fibers (4a), (4b) are pressed from the upside of the bare optical fibers (4a),(4b) at the tip end side of the array, and they are placed and fixed in the array guide grooves. A filter insertion groove (17) is formed in the direction crossing the corresponding array guide grooves (22) at an area where the array guide grooves (22) are formed, a filter (16) is inserted into the filter insertion groove (17), and the filter (16) is attached to each of the second bare optical fibers (4b) at the second optical fiber tape (6b) side.
