PROBLEM TO BE SOLVED: To produce a glass material which is suitable for bringing about poling effect in particular as for poling technology utilized for forming a nonlinear optical element used in an optical communication field or the like, and to provide a glass composition thereof. SOLUTION: The glass composition for poling comprises monovalent metal of 0.001 to 0.5 mol% expressed in terms of oxide and Al 2 O 3 of 0.1 to 40 mol%. The ratio between the molar number of the Al 2 O 3 and the total molar number of the monovalent metal oxide is ≥1.0. As the monovalent metal, one or more kinds selected from Li, Na, K, Cs, Ag, Cu and Au are preferably added. COPYRIGHT: (C)2004,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-applying device capable of pressing the surface of a rock crystal uniformly in a hot press method. SOLUTION: An upper block 12 comes into contact with a bearing block 20, and the bearing block 20 is connected to an upper plate 21. The upper block 12 has a projected part 22 on its upper surface, which has been processed into a convex face having a radius R1. The bearing block 20 has a recessed part 23 on its rear surface, which has been processed into a concave face having a radius R2 (R2>R1). Thereby, the pressing face of the upper pressing plate 15 surely comes to imitate the face of the rock crystal substrate 11 at the time of pressing, and a uniform load is impressed to the rock crystal substrate 11.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of patterning and fabricating poled dielectric microstructures in dielectric materials. SOLUTION: The poled dielectric microstructure is formed within the dielectric material. The poled dielectric microstructure is then segmented into a plurality of independent sub-structures. The poled dielectric microstructures are then fabricated within each of the plurality of the independent sub-structures. Further, additional processes and a novel poling setup for improving and implementing the patterning and fabrication method are also disclosed. COPYRIGHT: (C)2004,JPO
