Consequently, the part of the light guide 4 has higher refractivity than that of the circumference, so incident light 5 propagates along the light guide 4. At this time, the free carrier density of the silicon thin film 2 is set below 10<18>cm<-3> in order to decrease propagation loss with 1.3-1.5mum wavelength. Further, since the semiconductor single- crystal thin film is used for the light guide, it is connected easily to a driving electric circuit and the efficiency of an optical control device is improved.

IPC: H04N5/33
Filed: 1980-11-25
Abstract: PURPOSE:To suppress noise generation by trapping undesired carriers which are produced on the reverse side of a semicondutive substrate in such a construction as an infrared ray detector and a signal transmitter are formed on the main surface, while an imperfect region is formed on the reverse side. CONSTITUTION:An infrared ray detector 2 consisting of a metal 2b which forms Schottky junction 2a and a CCD3 where a potential well 5 is formed for storing signal charges are provided on the main surface of a p type silicon substrate 1. On the other hand, an imperfect region 6 is formed by irradiation and injection of charged elementary particles such as protons from the reverse side at which light rays to be detected 4 arrive. Thus, noise can be eliminated by this construction where carriers which are produced by undesired components of detected light rays (such as visible rays that have no connection with temperature) are caused to be trapped on the reverse side so that those do not reach the signal transmitter on the main surface.
