Random laser generation, spectrum synchronization and code sharing method

Abstract

The invention discloses a random laser generation, spectrum synchronization and coding sharing method, which is realized through an optical fiber type disordered microcavity cascade structure. A pulse pump light source irradiates network nodes in a optical fiber type disordered microcavity cascade structure to generate random laser; the coupling efficiency between adjacent network nodes is adjusted to realize random laser spectrum synchronization; and binary coding is performed on the random laser spectrum, so that different network nodes in spectrum synchronization can synchronously output the same binary code string, and coding sharing is realized. The optical fiber type disordered microcavity cascade structure provided by the invention can generate multi-point associated random laser, and the output random laser is narrow in spectral line width, wide in emission wavelength range and easy to network and interconnect; the problem that an original random laser system is difficult to interconnect and synchronize is solved, and an effective method is provided for output synchronization of a random radiation system. Spectrum coding and code sharing based on random laser spectrum synchronization are a physical layer random code generation and information sharing method.

Description

technical field [0001] The invention belongs to the field of optical laser and optical information, in particular to a random laser generation, spectrum synchronization and code sharing method. Background technique [0002] Disorder and disorder are unavoidable in both natural and artificial environments, and light-light or light-matter interactions in disordered and disordered systems can produce complex optical phenomena, such as symmetry breaking, random lasing, chaos , Strange waves and neuron-like phenomena. Manipulating these phenomena in complex optical structures holds great promise in applications such as spectroscopy, imaging, sensing, secure communications, neural networks, and the Internet of Things. [0003] Optical microcavities are an important part of many photonic applications and can generate optical modes or lasing with ultra-high quality factor and low threshold power, however, exploiting this output usually requires complex evanescent coupling and harsh...
