Random numbers are crucial in the generation of cryptographic keys for classical and quantum cryptography systems, the reliability of modern networked society, and stochastic simulation, etc. Our findings provide a novel and easy method to create controllable and robust optical chaos for high-speed random number generation. The internal mode interaction and corresponding carrier spatial oscillations pave the way of mode engineering for nonlinear dynamics in a solitary laser. By adjusting mode frequency interval close to the intrinsic relaxation oscillation frequency, nonlinear dynamics including self-chaos and period-oscillations are predicted and realized numerically and experimentally due to internal mode interaction.

Here, we demonstrate the first self-chaotic microlaser based on internal mode interaction for a dual-mode microcavity laser, and realize random number generation using the self-chaotic laser output. Nevertheless, chaotic lasers under external feedback are hindered by external feedback loop time, which causes correlation peaks for chaotic output. Upon review and approval, IT staff will then pull the class roll and grant access.Chaotic semiconductor lasers have been widely investigated for generating unpredictable random numbers, especially for lasers with external optical feedback.statement that the COMSOL CKL will only be used for instruction and will not be used for research.In order to gain access to COMSOL, faculty members in COE must request access for their class by emailing the ITECS Service Desk with the following info:.It is only for in-class instructional use and associated homework. This license may not be used for research. It is installed on the 'EOS-Lab' WVD environment, but is only visible to students whose faculty have requested access per the below process. This license is for instructional use only, and is only available via WVD.Our license includes 30 concurrent seats of the main COMSOL Multiphysics software, plus 30 concurrent seats for each of the following modules: The College of Engineering has a Class Kit License (CKL) for COMSOL.
