The present invention belongs to the technical field of photonic integrated chips, and more specifically, relates to a reconfigurable photonic integrated chip based on a phase change material film and a processing method therefor. A phase change material film is processed with femtosecond laser and continuous laser to change its surface phase state distribution; and by customizing the number of pulses, power and the like of the laser for processing, and a pattern shape for processing, a specific surface phase state distribution is achieved, so as to achieve the function of a specific photonic integrated chip.
