Speech Title: Photonic integrated semiconductor laser chip for broadband chaos generation
Abstract: Laser chaos has been widely used in various fields. However, it should be noticed that in most schemes for laser chaos generation are constructed using the discrete optical components, that are usually bulky, lack of long-term stability and reproducibility. Photonic integrated circuits (PIC) is a promising technology to overcome these issues and few chaotic PIC schemes has been reported. However, most of them are based on the optical-feedback structure, that would inevitably bring about time delay signatures (TDS). In this letter, we propose a novel photonic integrated chaotic semiconductor laser (PICSL). This chip consists of two back to back DFB lasers to form a mutual coupled structure. It can generate laser chaos with the standard bandwidth above 7.0 GHz and the TDS is totally suppressed. Meanwhile, the route into chaos is confirmed through the observation of diverse nonlinear dynamics.
