Summary:
Chaotic semiconductor lasers with delayed optical feedback have been used for fast physical random-bit generation. It has been reported that, for obtaining strongly chaotic states desirable for random-bit generation, a long enough external cavity (e.g., 2 mm) for delayed optical feedback is necessary. This requirement is an obstacle to miniaturization of the device. As an idea to resolve this problem, folding an optical path in a two-dimensional (2D) external cavity has been proposed. In this presentation, we report the optimal design of the 2D external cavity shape where the light intensity of the delayed optical feedback is increased up to 8.9\% more than that of the previously proposed 2D external cavity.
