| description | Axially uniform optical fibers provide a low-cost, scalable platform for the emission of whispering gallery mode (WGM) lasers. This paper proposes a method for generating and controlling WGM lasers based on the design of a flexible optical fiber array structure. By adjusting the spacing between the flexible fibers, the coupling relationship between different WGM modes is modulated, achieving a transition from regular to random WGM (R-WGM) mechanisms. Additionally, the application of this laser in information security encryption is demonstrated and explored. |
