ABSTRACT:
An optical quantizing unit includes an optical divider dividing 1stoptical pulses to be quantized and sending the divided 1stoptical pulses into a plurality of paths; a plurality of optical filters passing with different transmittances the divided 1stoptical pulses; and an optical threshold filter sequentially receiving the 1stoptical pulses, and sending 2ndoptical pulses when light intensities of the 1stoptical pulses are above a preset threshold value.
