中文摘要：
基于自旋反转模型,对双光注入下1550nm垂直腔表面发射半导体激光器（1550nm-VCSEL）的非线性动力学行为进行了理论分析和数值仿真研究.结果表明：当一个中心波长位于1550nm的副VCSEL（S-VCSEL）同时受到来自两个主VCSELs（M-VCSELs）的光注入时,在适当的注入条件下,S-VCSEL可处于双光注入锁定态.此时,S-VCSEL中的两偏振模式均呈现频率为两注入光频率之差的周期性振荡,输出的光谱仅包含两个主频率部分,即光谱具有单边带特征.因此,基于双光注入下S-VCSEL的周期性振荡可以获得两个相互正交的光毫米波.通过调节两个M-VCSELs之间的频率差异可使毫米波频率在较大范围内连续可调,通过调节系统参量可以控制毫米波功率以及调制深度.
英文摘要：
Based on the spin-flip model,the nonlinear dynamics of a 1550 nm vertical-cavity surface-emitting laser（1550 nm-VCSEL）subject to dual-beam optically injection is investigated theoretically.The results show that a slave 1550 nm-VCSEL（S-VCSEL）under the injection of dual-beam output from two master VCSELs（M-VCSELs）can be driven to enter into an injection locking state under suitable injection parameters.In this case,the outputs of both X and Y polarization modes of the S-VCSEL exhibit periodic oscillation whose frequency is equal to the frequency detuning between the two M-VCSELs,and its optical spectrum contains only two main frequency components and possesses a single sideband spectrum structure.As a result,two mutually orthogonal optical millimeterwaves can be obtained based on the periodic oscillation in a VCSEL subject to dual-beam optically injected locking.Through adjusting the frequency detuning between the two M-VCSELs,the frequency of the millimeter-wave can be tuned continuously in a large range,while the power and modulation depth can also be controlled by adjusting the system parameters.
