A method for designing a multi-layer optical structure includes: obtaining candidate multi-layer optical structures through a sequence generator; obtaining a candidate spectrum for each candidate multi-layer optical structure; obtaining a difference between the candidate spectrum and a target spectrum; updating sequence generator parameters through reinforcement learning training and iteratively performing the obtainings and the updating in response to a first termination condition being not met; and selecting one of all obtained candidate structures to be a target multi-layer optical structure in response to the first termination condition being met. The difference between a spectrum of the target multi-layer optical structure and the target spectrum is minimized through the process. The method of the present application can perform the designs robustly and effectively.
