The design details of an integrated optical fast D–A converter are presented. Nine directional couplers with identical electrode lengths are utilized in the design of an 8-bit two’s complement, bipolar system. This D–A converter compares very favorably with respect to Mach-Zehnder systems as far as size, flexibility, and bipolar capabilities are concerned. Fast D–A conversion and analog switching may be particularly desirable for optical interconnection and computing networks.
