WAVEGUIDES BENDS CREATION METHOD Russian patent published in 2018 - IPC G02B6/10 

FIELD: optics.

SUBSTANCE: invention relates to the field of integrated optical waveguide microstructures creation for application in the information receiving, processing and transmitting systems via optical communication channels and other fields of science and technology. Waveguide in the integrated optical circuit bending formation method consists in formation in the solid workpiece with at least one plane face, of transparent for the predetermined wavelengths range waveguide rectilinear portions, which axes are located in the same plane with the normal to the face at the same angles to the said face, and the reflecting surface arrangement on this face. At that, the waveguide sections are formed by the laser radiation focusing in the workpiece volume, and their axes intersection point is located inside the workpiece and is separated from said flat face at a distance of not more than 1/10 of the workpiece maximum linear dimension.

EFFECT: reduction of optical signals losses passing through the waveguides bends, which are created by the method of printing in the solid clear glass volume.
