Polarization switching and its hysteresis behavior of VCSELs controlled by injection current has been widely known. In this study, we investigate novel polarization switching and its hysteresis behavior of a VCSEL controlled by external magnetic fields, in other words, by precession frequency of electron spins in the VCSEL. This phenomenon is attributed to coupling of two orthogonal linear polarization modes due to the precession of electron spin noise.
