Abstract

The present application relates to a beam chaos synchronization control method based on a self-feedback transverse coupling laser, comprising: injecting a laser array that is self-feedback through a plane mirror into the drive transverse coupling laser, and outputting the incident beam; injecting the incident beam into In the response transverse coupling laser, controlling the injection mode of the incident beam into the response transverse coupling laser, and obtaining the output beam output from the response transverse coupling laser, so that the incident beam and the exit beam are completely chaotic Synchronize. Through this method, controlling the injection mode of the incident beam into the responsive transverse coupling laser can realize high-quality complete chaos synchronization control of all laser elements under different self-feedback conditions for driving the transverse coupling laser.

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...
