In this paper, an integratable spectrum quantization schema for all-optical analog-to-digital conversion (AOADC) is demonstrated in Ge11.5As24Se64.5 rib film waveguide by slicing the supercontinuum. Owing to the high nonlinearity coefficient of 137.8 W-1m-1, the input pulse peak power are very low which varies from 540 to 900mW and then the broadened spectrum is filtered with an arrayed waveguide grating. As a result, 4-bit quantization resolution along with effective number of bit (ENOB) of 3.985 and a signal-to-noise ratio of 23.99 dB are achieved. It is believed that this proposed schema is suitable for integratable AOADC with low power consumption.
