Optical computing system, computing compensation method, and photonic integrated circuit chip

A method for compensating optical computing results, comprising:

• splitting a light wave input into an optical computing system into a first branch and a second branch according to a predetermined ratio using a beam splitter;
• transmitting the light wave of the second branch to a computing module of the optical computing system, wherein the computing module is configured to modulate an electrical signal onto the light wave of the second branch to generate an optical signal and perform computation on information represented by the optical signal;
• monitoring the light wave of the first branch in real time to obtain monitoring results;
• and
• performing a compensation operation on computing results output by the computing module based on the obtained monitoring results.
