A chip-scale chaotic laser system with optoelectronic delayed feedback is proposed and analyzed by numerical simulation. This chip eliminates the need for bulky delay components such as long optical fibers, free propagation external cavities, relying solely on internal devices waveguides to achieve delay. approach simplifies integration, maintaining a compact size. According results, exhibits rich dynamics, including periodicity, quasi-periodicity, states. Chaos resembling Gaussian white noise achieved picosecond-level time, highlighting complexity of signals. Furthermore, time signature (TDS) concealment enhanced short comparable inverse bandwidth τ, albeit at cost sacrificing signal complexity. Applying photonic integrated circuits practical applications, 1 Gbps back-to-back communication transmission feasible. Results demonstrate low bit error rates (BERs) authorizers (<10
