An optical waveguide including a first cladding layer; a core layer, including first and second core sections with cladding sections on sides thereof in the in-layer direction; and a second cladding layer. A refractive index distribution in the in-layer direction in the core layer, from the first core section to an adjacent cladding section, has a continuous change and a region with a first peak, a first dip, and a second peak in this order; the first peak at a position of the first core section, the second peak with a maximum value of refractive index smaller than of the first peak, at a position of the cladding section, and a portion, from the first cladding layer to the first core section, corresponded to a refractive index distribution in the layer-stacking direction, discontinuously changing at the boundary between the first cladding layer and first core section.

A half mirror has a shape on a substrate and excels in appearance and design and is fabricated by a method. The method includes forming an organic film by applying, onto a transparent substrate or film, a primer composition containing an addition-polymerizable compound having three or more reactive groups, an addition-polymerizable compound having an acidic group, and an addition-polymerizable compound having a hydrophilic functional group, and polymerizing the primer composition. The method includes turning the acidic group into a metal (M1) salt by treating the organic film with an aqueous solution containing metal (M1) ions, and turning the metal (M1) salt into a metal (M2) salt by treating the organic film with a metal (M2) ion aqueous solution containing metal (M2) ions that are lower in ionization tendency than metal (M1) ions, and (d) reducing metal (M2) ions to form a metal film on a surface of the organic film.

An optical waveguide structure has excellent heat resistance and a low water absorbing property and can be manufactured with a low material cost. Such an optical waveguide structure includes: an optical waveguide having two surfaces, a core layer including core portions and cladding portions each having a refractive index lower than that of each of the core portions, the core layer having two surfaces, and cladding layers provided so as to make contact with the two surfaces of the core layer and having a refractive index lower than that of each of the core portions; and conductor layers provided on the two surfaces of the optical waveguide. In the optical waveguide structure, each of the cladding layers is formed of a norbornene-based polymer as a major component thereof. Further, it is preferred that the norbornene-based polymer is composed of molecules each represented by the following formula 1 as a major component thereof: wherein R is an alkyl group having a carbon number of 1 to 10, “a” is an integer of 0 to 3, “b” is an integer of 1 to 3, and “p”/“q” is 20 or less.

An exposure apparatus includes an image sensor, a measurement optical system configured to guide measurement light to obliquely enter the projection optical system, and further, to guide the measurement light returned from the projection optical system to the image sensor, and a control unit configured to calculate surface position information of the substrate based on the output from the image sensor. The control unit calculates the surface position information of the substrate based on an interval between the image, of a mark arranged on the original stage, formed by the measurement light, which has passed through the mark, and the image of the mark formed by the measurement light reflected by the mark.

N-Acetyl-D-glucosamine can be produced by cultivating a fungus capable of producing N-acetyl-D-glucosamine, such as Trichoderma hamatum AB10282 strain (FERM BP-10623) or Trichoderma harzianum AB10283 strain (FERM BP-10624), in a culture medium supplemented with a carbon source other than chitin and chitin oligosaccharide and a nitrogen source to produce and accumulate N-acetyl-D-glucosamine in the culture medium and then collecting N-acetyl-D-glucosamine from the culture medium.
