Abstract

Semiconductor lasers in chaotic oscillations have recently been utilized for random bit generation at output rates exceeding gigabits per second, which are important for high-speed numerical simulation, encryption, and communication. Although chaotic signals were successfully invoked though optical feedback into the lasers, the feedbacks inherently led to residual autocorrelation that is detrimental to the output randomness. In this paper, we experimentally demonstrate random bit generation using an optically injected semiconductor laser without feedback. Through oversampling the signal at 10 GHz as recorded by a 2.5-GHz oscilloscope, random bit generation at 40 Gbps is attained from extracting 4 bits per sample.© 2012 SPIE.
