Zusammenfassung:	An optical digital to analog converter having a plurality of input channels, each having the presence or absence of light representing the respective ones or zeros of a digital code, each of the input channels being coupled to a channel consisting of cascaded magneto-optical mode converters, the number of cascaded elements being equal to the corresponding weighting value of the element of the code, and a common receptor to which the outputs of the cascades are coupled.
