The invention discloses an optimization method of a micro-nano optoelectronic device and an on-chip modular division multiplexer/demultiplexer, and the method comprises the following steps: building an initial simulation model of the device, and calculating the quality factor value of the whole simulation model at the moment; selecting a movable vertex of the initial polygon as a search point, and calculating a quality factor value once when the position of the search point is changed once; searching the position of a search point enabling the quality factor value to be optimal; the positions of the search points are kept at the positions where the quality factor values are optimal, the next search point is searched, and all the search points search the optimal positions once as iteration; and iteration is repeated until a set index is reached. According to the optimization method, the optimization speed is high, and a large amount of calculation time and calculation resources can be saved; the shape searchin
