光孤子是实现通信线路的理想平台，因为它们可以彼此非常接近地封装，而不会由于它们的相互作用而导致编码信息的部分丢失。另一方面，光孤子之间的相互作用是实现计算和全光信息处理的必要条件。在这里，我们研究了亮耗散极化孤子如何相互作用，并利用它们的相互作用来实现与或门与最先进的技术。此外，我们还证明了孤子-孤子相互作用可以用来确定描述自旋相反的极化激元之间相互作用的参数α（2）的符号。
Optical solitons are an ideal platform for the implementation of communication lines, since they can be packed extremely close one to another without risking partial loss of the encoded information due to their interaction. On the other hand, soliton-soliton interactions are needed to implement computations and achieve all-optical information processing. Here, we study how bright dissipative polariton solitons interact and exploit their interaction to implement AND and OR gates with state of the art technology. Moreover, we show that the soliton-soliton interaction can be used to determine the sign of alpha(2), the parameter describing the interaction between polaritons with opposite spin.
