Abstract
An optical digital to analog converter (oDAC) that may include (a) multiple optical paths that are parallel to each other; (b) a combiner, (c) a splitter that is configured to receive an optical signal at a splitter input and split the optical signal between multiple splitter outputs to provide multiple path input signals to the multiple optical paths. The multiple optical paths are configured to optically process, in parallel, path input signals to provide path output signals. Each optical path is configured to apply an optical process that comprises applying optical modulation, by an optical gate of the optical path and under a control of an electrical modulator, to provide an optical signal having a value selected out of multiple constellation levels. The combiner is configured to add the multiple path output signals to provide an oDAC output signal having a value selected from values of a single quadrature constellation.
