We propose a new, to our knowledge, method for an all-optical analog-to-digital converter by using self-frequency shifting in a fiber and a pulse-shaping technique. Preliminary experimental results show that various digitized temporal bit signals can be generated by the variation of the power of an ultrashort analog input pulse of less than 1 ps.
