Abstract
A digital-to-analog converter (DAC) includes multiple electro-optical converters to generate multiple first optical signals in response to multiple input signals, multiple optical attenuators to attenuate intensities of the first optical signals and to generate multiple second optical signals, an optical coupler to combine the second optical signals and to generate a third optical signal, and a photodetector to convert the third optical signal into an electrical analog signal.
