Toward a higher degree of secure communication, great efforts have been made to develop encryption and anticounterfeiting strategies. In particular, optical encryption with high complexity has become one of the most significant approaches. To strengthen optical information security, the concept of a spectral encryption approach is proposed based on selectively visualized spectral modes in random lasers. By coupling with external whispering gallery mode cavity, hidden localized lasing modes with special multiple-peaks spectra are selected from phase-correlated random lasers with smooth single-peak spectra. The selectively visualized localized modes are utilized for spectral encryption of secure information. The encoded spectral modes that are hidden in phase-correlated modes with identical spectra can only be selectively recognized by a special external coupler. This multiplex encryption strategy is super for the simple operation, low cost, and high security, supplying a new approach for further applications in secure communication and anticounterfeiting.

选择性可视化随机激光器中的隐藏模式以实现安全通信

为了实现更高程度的安全通信,人们付出了巨大努力来开发加密和防伪策略。尤其是复杂度高的光学加密已成为最重要的方法之一。为了加强光信息安全,提出了一种基于随机激光器中选择性可视化光谱模式的光谱加密方法的概念。通过与外部回音壁模式腔耦合,从具有平滑单峰光谱的相位相关随机激光器中选择具有特殊多峰光谱的隐藏局部激光模式。选择性可视化局部模式用于安全信息的频谱加密。隐藏在具有相同光谱的相位相关模式中的编码光谱模式只能由特殊的外部耦合器选择性地识别。这种多重加密策略具有操作简单、成本低、安全性高的优点,为进一步在安全通信和防伪方面的应用提供了一种新的途径。
