摘要： A method for producing a reaction product, with which the reaction product is obtained from a starting material through a particular organic synthesis reaction, the method includes (a) a step of setting a target wavelength to a peak wavelength of a reaction region involved in the organic synthesis reaction in an infrared absorption spectrum of the starting material; (b) a step of preparing an infrared heater that emits an infrared ray having a peak at the target wavelength from a structure constituted by a metal pattern, a dielectric layer, and a metal substrate stacked in this order from an outer side toward an inner side; and (c) a step of obtaining the reaction product by allowing the organic synthesis reaction to proceed while the infrared ray having a peak at the target wavelength is being applied to the starting material from the infrared heater.

摘要： An optical element includes an optical waveguide layer. The optical waveguide includes a periodic structure of grooves. The optical waveguide layer has a layer-thickness equal to or greater than 1.5 μm and is made of material selected from a group consisting of Ta2O5, Al2O3, LiNbO3, LiTaO3, AlN, GaN, SiC, and Yttrium aluminum garnet (YAG). (D/0.5Λ)≥2.5 is satisfied where D indicates the depth of groove; and Λ indicates the pitch of the arranged grooves in the periodic structure. The unit of Λ is identical to the unit of D.

摘要： It is provided an assembly including an optical material layer composed of a metal oxide, an underlying layer provided over the optical material layer and composed of a metal or a metal silicide, and a resin layer provided over the underlying layer. A mold including a design pattern corresponding with the fine pattern to the resin layer of the assembly to transcript the design pattern to the resin layer. The resin layer and underlying layer are etched to form an opening in the resin layer and underlying layer to expose the optical material layer through the opening. The optical material layer is etched using the underlying layer as a mask to form the fine pattern in the optical material layer.
