实验研究了保偏和选偏光注入的单向耦合垂直腔面发射激光器（VCSELs）中混沌信息的编码和解码。利用保偏光注入技术，在混沌发射机中成功地编码了一个GHz的信息，并从接收机中解码了该信息。相比之下，使用偏振选择光注入的解码仅在330 MHz下实现。研究还表明，正反混沌同步都可以实现GHz报文提取，从而为利用vcsel的极化特性进行双工混沌报文传输提供了机会。
Chaotic message encoding and decoding in unidirectionally coupled vertical-cavity surface-emitting lasers (VCSELs) with polarization-preserved and polarization-selected optical injection has been studied experimentally. A GHz message has been successfully encoded in the chaotic transmitter and decoded from the receiver with polarization-preserved optical injection. In contrast decoding using polarization-selected optical injection was achieved at only 330 MHz. It has also been demonstrated that GHz message extraction can be achieved using both normal and inverse chaos synchronization thus providing an opportunity for exploiting polarization properties of VCSELs for duplexed chaotic message transmission.
