Abstract

A deformed square microcavity laser, based on internal mode interactions, exhibits spontaneous chaotic behavior without external disturbances. Unlike traditional methods that rely on photodetectors for photoelectric conversion, we propose and demonstrate a novel approach to directly extract chaotic signals from the laser's P-electrode. This scheme successfully extracts the chaotic electrical signal with a 4.4GHz bandwidth. Our approach offers advantages in cost-effectiveness and simplicity. It holds promise for applications such as high-speed physical random number generation and radar detection.
