20130178005 | OPTICAL ELEMENT MODULE AND METHOD OF MANUFACTURING THE SAME - A method of manufacturing an optical element module in which an optical element and a semiconductor circuit element are mounted on one surface of a silicon substrate, a mirror surface inclined at approximately 45 degrees is formed on the other surface, and an optical fiber facing the mirror surface is disposed in a V groove formed along the other surface, the method of manufacturing includes the steps of forming the mirror surface and V-shaped side surfaces of the V groove simultaneously by first crystal anisotropic etching on the other surface, and forming an attaching surface substantially perpendicular to the one surface and the other surface, which is formed at an end side of the V groove, and for attaching an end of the optical fiber, by second crystal anisotropic etching in a crystal plane orientation different from that of the first crystal anisotropic etching. | 07-11-2013 |
20140027642 | INFRARED IMAGE SENSOR AND SIGNAL READ METHOD - Provided is an infrared image sensor for detecting infrared rays. The infrared image sensor includes a light-receiving unit including a pixel region in which a plurality of pixels are arranged and at least one reference pixel; a difference circuit for acquiring a first differential signal that is a differential signal between a signal of one pixel contained in the pixel region and a signal of the reference pixel and a second differential signal that is a differential signal between signals of two predetermined pixels out of the pixels contained in the pixel region; and a pixel signal calculating unit that calculates a signal of each of the pixels on the basis of the first differential signal and the second differential signal. | 01-30-2014 |
20140104687 | PRODUCTION METHOD FOR OPTICAL COMPONENT AND OPTICAL COMPONENT - A method for manufacturing a light transmissive optical component, includes a first etching process of forming a depressed portion by applying etching to a silicon region of a plate-shaped member, a thermal oxidation process of forming a silicon oxide film by thermally oxidizing an inner side surface of the depressed portion, and a nitride film formation process of forming a silicon nitride film that covers the silicon oxide film. Accordingly, it is possible to realize a manufacturing method for an optical component which is capable of uniformly forming a silicon oxide film on a semi-transmissive reflecting surface which is largely inclined (or nearly vertical) with respect to a substrate surface, and an optical component produced by this method. | 04-17-2014 |
20140139924 | OPTICAL MODULE AND PRODUCTION METHOD FOR SAME - An optical module includes a first plate-shaped member having a light transmissive optical component which is formed by applying etching to a silicon region, and a second plate-shaped member having light reflective optical components (mirrors) for reflecting light transmitting through the light transmissive optical component. The first and second plate-shaped members are bonded to one another, and an optical path for light transmitting through the light transmissive optical component is along a component forming surface of the first plate-shaped member and a principal surface of the second plate-shaped member. Thereby, realizing an optical module in which it is possible to dispose the light reflective optical component and the light transmissive optical component close to one another, and a manufacturing method for the optical module. | 05-22-2014 |
