Recently, fast physical random-number generators using chaotic lasers have been proposed. However, most previous schemes using chaotic lasers schemes are bulky to implement. Random number generation using a photonic integrated circuit (PIC) with 10-mm-long external cavity for fast chaos generation has been demonstrated. In this study, we investigated the condition for generating fast random numbers for different sampling rates using a PIC with 5-mm-long external cavity. We also used PICs with different external cavity lengths and generated random bit sequences at various sampling rates. We can generate random bits at rates up to 5.56 Gb/s using a PIC with 4-mm-long external cavity. |
