Time-interleaved sampling analog-to-digital conversion utilizing photonic radio frequency memory

“…A variety of devices such as dispersion compensating fiber, electro-optical crystal, and reflective diffraction grating are used to achieve the time stretching of signals [2,3] . Multiple channels can scale the sampling rate with time-interleaved sampling technology [4][5][6] . Using an optical frequency comb and a directly-modulated laser can enhance the digitization of large bandwidth signals [7][8][9] .…”
