A novel amorphous optical device contributes to economic construction of optical computers. Since economic parallel processing of signals such as image information is made possible, the novel amorphous optical device contributes also to development of optical computers capable of performing ultra-high speed and parallel processing, object recognizing apparatuses in which image optical signals are processed by using image optical signals, motion picture extracting apparatuses used for eyes of robots and object movement monitors and optical surge absorbers. An amorphous optical device which is doped with an element having a negative optical input-output characteristic to incident light, wherein the number of ions and/or atoms of the element is 1x1026 to 2.8x1028 per 1 m3 of an amorphous material, and has a negative optical input-output characteristic to incident light, an amorphous optical device which comprises amorphous optical device described above and shaped two dimensionally and controls image optical signals directly by using image optical signals and an amorphous optical device described above which uses light obtained by spectrally splitting or filtering the sunlight, thermal radiation light or light emitted from a fluorescent material by electrons emitted by electric field, or laser light as the light source are provided.
