We propose to investigate the dynamic properties of optically injected spin-polarised, vertical-cavity surface-emitting lasers (VCSELs). In general spin-polarised lasers offer many attractive advantages, including enhanced intensity and polarisation stability as well as a reduced threshold current, and they have potential applications in cryptographic communications and reconfigurable optical interconnects. Moreover the nonlinear dynamics of optically-injected semiconductor lasers has been a fertile research topic for many years and the benefits are now emerging in stable injection-locked sources with very high bandwidths as well as in potential applications in encrypted communications systems based on chaos. However, the novelty of this proposal lies in combining the hitherto disparate fields of spin-polarised VCSELs and optical injected lasers, examining particularly the effects of polarised optical injection on the nonlinear dynamics of spin-polarised lasers.

本文研究了光注入自旋极化垂直腔面发射激光器（VCSEL）的动态特性。一般来说，自旋偏振激光器提供了许多有吸引力的优点，包括增强的强度和偏振稳定性以及降低的阈值电流，并且它们在密码通信和可重构光学互连中具有潜在的应用。此外，光注入半导体激光器的非线性动力学多年来一直是一个丰富的研究课题，现在的好处是在稳定的注入锁定源具有非常高的带宽，以及在基于混沌的加密通信系统的潜在应用。然而，该提案的新奇在于将迄今为止不同的自旋极化VCSEL和光学注入激光器领域相结合，特别是研究极化光学注入对自旋极化激光器的非线性动力学的影响。
