专利汇可以提供Photoelectric converter专利检索,专利查询,专利分析的服务。并且PURPOSE:To monitor optical energy in an on-line mode, by combining thermoelectric effect of a junction part formed by semiconductors and the like and a light absorbing characteristic of a light transmitting semiconductor. CONSTITUTION:A thin film 3 performs light absorbing action and heating action and forms a thermocouple together with a thin film 4, which is provided to form a pair. For example, by using an embedded type light transmitting path, a part of a light transmitting path is removed by etching. The removed recessed part is buried by the P type amorphous silicon thin film 3, which is deposited on a ferrodielectric substrate. The thin film has a light absorbing characteristic and wavelength dependence. The P type thin film 3 in the vicinity of the recessed part is heated by the absorption of laser light and the temperature becomes high. The N type thin film 4, which is provided so as to contact with a part of the P type thin film 3 in the vicinity of the recessed part, forms a thermocouple together with the P type thin film 3. The vicinity of the recessed part forms a hot junction. The electrode pair, which is provided so that the pair is separated from the thin films, forms a cold junction.,下面是Photoelectric converter专利的具体信息内容。
