Optical Injection Dynamics of VCSEL Frequency Combs

Recent works have shown the possibility to control through optical injection frequency combs generated by gain switching in Vertical-Cavity Surface-Emitting Lasers (VCSELs) [1]. The opposite situation, in which VCSEL is subject to injection of an optical frequency comb (OFC) deserves close attention and has not been addressed so far. In this work, we analyze the nonlinear polarization dynamics of a single-mode VCSEL with optical injection. Here, we select and reveal several bifurcations scenarios leading to generation of a two polarization OFC.
