| Summary: | Optoelectronic AND, OR and NOT logical gates were composed of thin film photoconducting and electroluminescent elements, made of cadmium sulphide and zinc sulphide, respectively, doped with copper, chlorine and manganese. The gates consisted of several photoconducting elements and one electroluminescent element suitably connected and supplied with a sinusoidal voltage. In such circuits the functions of product, sum
and negation for input light signals illuminating the photoconducting elements were realized, and the output signal was the light emitted by the electroluminescent element. |
