This study proposes a array structure of one-dimensional vertical cavity surface emitting laser that utilizes the Talbot effect (Talbot VCSEL) to generate independent multi-channel chaotic signals. By extending the optical feedback rate equation, we numerically investigate the chaotic correlation of the Talbot VCSEL array under various conditions, including different feedback coefficients, optical coupling ratios, and filling factors. The results indicate that the number of coupling channels and the optical coupling ratio are influenced by the filling factor. Notably, a one-dimensional Talbot VCSEL array can produce chaotic signal output from 25 laser units within the weak light feedback range, with a feedback coefficient of less than 10 ns^-1 and a filling factor of 0.7 to 1.0. Each channel exhibits low correlation, and the signal peak sidelobe level remains below 0.5.
