Combined with the time delay reservoir computing and vertical cavity surface emitting laser, based on the existing fiber optic platform, an experimental study on the time delay reservoir computing system with the 1 550 nm waveband vertical cavity surface emitting laser as the nonlinear node is carried out. The results show that a Santa-Fe chaotic time series prediction task and a single nonlinear channel equalization task can be successfully implemented in the experimental system. Based on the vertical cavity surface emitting laser that can achieve two polarization modes coexistence under certain parameter conditions, external signals are further injected into the two polarization modes of vertical cavity surface emitting laser simultaneously, and the parallel processing of Santa Fe chaotic time series prediction and signal nonlinear trace equalization is successfully completed, however, the performance of parallel tasks processing is weaker than the performance of single task processing. Besides, the performance of the parallel task processing is improved with the increase of the external light injection intensity, and the performance of the side with the larger injection intensity ratio is better.
