Abstract

The invention relates to a light beam chaotic synchronization control method based on a self-feedback transverse coupling laser. The method comprises the steps of: injecting a laser array which carries out self-feedback through a plane mirror into a driving transverse coupling laser, and outputting an incident light beam; and injecting the incident light beam into a response transverse coupling laser, controlling an injection mode of injecting the incident light beam into the response transverse coupling laser, and obtaining an emergent light beam output from the response transverse coupling laser, so as to realize the completely chaotic synchronization of the incident light beam and the emergent light beam. By means of the method, the injection mode of injecting the incident light beam into the response transverse coupling laser is controlled, and high-quality complete chaotic synchronization control over all laser elements can be achieved for the driving transverse coupling laser under different self-feedback conditions.

Description

technical field [0001] The present application relates to the field of optics, in particular to a method for synchronous control of beam chaos based on self-feedback transverse coupling lasers. Background technique [0002] At present, people's research on one-dimensional transverse laser arrays focuses on different types of chaotic synchronization between two unidirectionally coupled and mutually coupled single lasers, such as full synchronization, generalized synchronization, real-time synchronization, and lead / lag synchronization. Laser arrays have the advantages of high power and enhanced modulation bandwidth, but also provide more controllable parameters, such as waveguide structure parameters, waveguide frequency, and coupling coefficient between two laser elements. However, when the 1D transverse laser coupled array is disturbed by external disturbances such as optical feedback and optical injection, these transversely coupled lasers exhibit complex and rich chaotic d...
