Optical digital-to-analog conversion |
摘要 |
An optical digital-to-analog conversion is realized by employing either a continuous wave or pulsed laser optical signal. The laser optical signal is split into a plurality of mutually coherent optical beams, which are phase shift modulated by bits of a digital data sequence to be converted to an analog signal. The phase shift modulated optical beams are recombined coherently to realize the desired digital-to-analog converted optical signal. <IMAGE>
