METHOD OF PRODUCING MEMBER WITH PERIODICAL STRUCTURE FINER THAN WAVELENGTH AND OPTICAL ELEMENT FORMED OF THE MEMBER

摘要

The present invention is laminated with a plurality of high refractive index layer and said plurality of said plurality of the low refractive index layer are alternately having a lower refractive index than the refractive index of the refractive index layers, each of the high refractive index layer and the low refractive index layer has a fine thickness than the wavelength in the method for producing the periodic structure member,; And by a second plurality of glass plates having a plurality of first plate glass with a lower refractive index than the refractive index of the first glass plate having a refractive index overlap each other to form a laminated member; Heating the lamination member for the lamination members to a temperature above the glass transition temperature; A step of applying pressure to the stacked member heated to a normal to the major surface of the glass, or by the tension of the main surface flat to the heated lamination member on the platen glass, while reducing the thickness of each plate glass integrating a lamination member to provide a method for producing the periodic structure member made. In this way, it is possible to, by forming the microstructure of the artificially controlled, produce a basic bulk member for forming an optical element having an optical refractive index distribution or optical anisotropy.
