The invention relates to an optical signal calculation device and an optical signal calculation method. The optical signal calculation device comprises a semiconductor substrate, a transmitting unit, a light splitting unit and a detection unit, and the transmitting unit, the light splitting unit and the photoelectric detection unit are sequentially prepared on the semiconductor substrate; the transmitting unit is used for transmitting optical signals, and comprises one or more first optical signals; the light splitting unit is used for splitting the first optical signals to generate multiple second optical signals; and the photoelectric detection unit comprises one or more photoelectric detectors and is used for receiving the multiple second optical signal groups to realize the photoelectric conversion. Light splitting is carried out by utilizing a diffraction effect, photoelectric signal conversion is carried out by utilizing multiple photoelectric detectors to obtain a plurality of electric signal data, and
