Chaos wavelength division multiplexing is a key technology to solve incompatibility between chaos secure communication and large capacity fiber data transmission. However, the existing integrated chaotic semiconductor laser can not achieve tuning in range. Here, wavelength-tunable chip has been designed fabricated. The consists of gain section, distributed Bragg reflector (DBR) grating optical amplifier (SOA) phase section. With feedback from reflective facet mode-beating composite cavities, emits laser. By adjusting current DBR grating, be tuned range 13.4 nm, central fine-tuned by region. Moreover, evolution periodic oscillation presented with variation SOA current. distribution dynamics bandwidth induced are investigated. This work explores for application communications.
