摘要： An optical switch having a small number of optical connections includes a substrate in which are provided a first light path for conducting optical signals and a second light path consisting of a photosensitive element and light emitting element in pairs. An optical fiber cable is interrupted by the substrate, and optical signals in the fiber cable are transmitted through the first light path or intervened by an electrical system through the second light path in response to the switching movement of the substrate.

摘要： In a device for coupling optically a light source with an optical transmission path, the present invention interposes an optical transmission path structure at the center of the distance between them in order to improve the optical coupling efficiency. The optical transmission path structure consists of a plurality of light transmitting elements arranged so that the light from the light source is received by the structure as incident light and is sent out therefrom as outgoing light at an outgoing angle which is equal to the angle of incidence. The light transmitting elements are arranged in parallel with the optical path of the light emitted from the light source and according to this arrangement, the system of the present device becomes equivalent to a system in which the positions of the light source are located at points of .+-.l.sub.1 from the light outgoing surface of the optical transmission path structure. When used with an optical fiber, the optical transmission path structure is disposed such that the distance from the light source to one end face of the optical transmission path structure is the same as the distance from the end face of the means for transmitting to the other end face of the optical transmission path structure.
摘要翻译：为了提高光耦合效率，在将光源与光传输路径光学连接的装置中，本发明将光传输路径结构设置在它们之间的距离的中心。光传输路径结构由多个透光元件组成，其布置成使得来自光源的光被该结构作为入射光被接收，并作为出射光从出射光发射出来，其出射角等于入射角。光传输元件与从光源发射的光的光路平行地布置，并且根据这种布置，本装置的系统变得等同于其中光源的位置位于 +/- l1从光传输路径结构的光出射表面。当与光纤一起使用时，光传输路径结构被设置为使得从光源到光传输路径结构的一个端面的距离与从传输装置的端面到另一端的距离相同光传输路径结构的端面。
