摘      要：Based on spin-flip model （SFM）, the nonlinear dynamics of 1550nm vertical-cavity surface-emitting lasers （VCSELs） subject to polarization-preserved optical feedback （PPOF） and orthogonal optical injection （OOI） are theoretically investigated. The results show that two linear polarization （LP） modes can be simultaneously stimulated and polarization switching （PS） can be observed, which is different from the case that only y LP mode exists in a VCSEL with PPOF. Under the joint action of PPOF and OOI, the two LP modes will exhibit rich dynamical states, such as period one, period two, multi- period and chaos oscillation. Different evolution routes to chaos can be also observed. Moreover, frequency detuning Af（Af=fm fs, wherefn andfs are the center frequencies of free-running master VCSEL and slave VCSEL, respectively） has an obvious influence on the PS. With the increase of the positive frequency detuning PS points shift toward larger injection strengths; meanwhile, a suitable negative frequency demning value makes the injection strength for PS be the lowest.
