| Outline of Final Research Achievements |
In this study, we developed a sub-mm2 sized laser chaos device with a two-dimensional microcavity structure for random bit generation. The main results are summarized as follows: (1) A laser device with an annular microcavity for delayed optical feedback was designed and fabricated. The laser device successfully generated chaotic outputs with a bandwidth of approximately 1 GHz. (2) The bit sequences that were generated from the chaotic outputs sampled at 0.78 GHz passed a standard statistical test suite for randomness, the Diehard test.
