实验研究了1550 nm垂直腔面发射激光器（1550 nm VCSEL）在正交光注入和光电负反馈作用下的非线性动力学特性。结果表明，在适当的正交光注入下，VCSEL可以表现出稳定态（S）、周期1（P1）、周期2（P2）、混沌（CO）、稳定注入锁定（SIL）和偏振开关（PS）等丰富的非线性动力学行为。进一步引入具有一定反馈延迟时间的光电负反馈后，对正交光注入1550 nm VCSEL的动态分布产生了显著影响，并观察到了包括三频准周期（Q3）态在内的一些新现象。随着光电反馈强度的增加，S和SIL区典型地缩小，而准周期（QP）和CO区扩大。
Nonlinear dynamic characteristics of a 1550 nm vertical-cavity surface-emitting laser (1550 nm VCSEL) simultaneously subject to orthogonal optical injection and negative optoelectronic feedback are experimentally investigated. The results show that, under suitable orthogonal optical injection the VCSEL can exhibit rich nonlinear dynamic behaviors such as stable state (S), period-one (P1), period-two (P2), chaos (CO), stable injection locking (SIL) and polarization switching (PS). After further introducing negative optoelectronic feedback with a certain feedback delay time, the dynamic distribution of the orthogonal optical injection 1550 nm VCSEL is significantly affected, and some new phenomena including three-frequency quasiperiodic (Q3) state can be observed. With the increase of optoelectronic feedback strength, the S and SIL regions typically are shrank, while the quasiperiodic (QP) and CO regions are enlarged.
