Cavity soliton (CS), a unique class of localized pattern inside a wide-area, driven cavity system is investigated from the perspective of mathematical modeling as well as applications in optical information technology. Possibility of generation of CSs is explored in different cavity systems; all having a vertical cavity surface emitting laser as the key component. Parametric space for the stability of the CS and the CS clusters is demarcated. The potential of using such CS as future ‘bits’ of information is elaborated. Schemes are developed to demonstrate how the cluster formation of CSs can be used to realize all-optical multilevel data encryption system. The role of nonlinear saturable absorber for the generation of CS is highlighted. In certain operating conditions the CSs exhibit spontaneous movement that basically owes to the gradients present in the system. Interaction dynamics of two or more CSs are investigated. Besides the regular ones the CSs show-off few unique dynamics like ‘all-optical push broom’ and ‘all-optical-marching’. The possibility and challenges to utilize the gradient-driven CS dynamics for the realization of ‘on-chip’ microscope are discussed.

VCSEL中的腔孤子：光学信息技术的单窗格解决方案

从数学建模以及在光学信息技术中的应用角度研究了腔孤子（CS），这是一类广域驱动腔系统内部的独特局部模式。在不同的腔系统中探索产生CS的可能性。它们都具有垂直腔表面发射激光器作为关键组件。划定了CS和CS群集稳定性的参数空间。阐述了将此类CS用作未来信息“比特”的潜力。开发了一些方案来演示如何将CS的集群形成用于实现全光多级数据加密系统。突出了非线性可饱和吸收体在CS生成中的作用。在某些操作条件下，CS表现出自发运动，这主要归因于系统中存在的坡度。研究了两个或多个CS的交互动力学。除了常规的CS外，CS还展示了一些独特的动力，例如“全光推扫帚”和“全光行进”。讨论了利用梯度驱动的CS动力学实现“芯片上”显微镜的可能性和挑战。
