Relative Intensity Noise of Vertical-Cavity Surface-Emitting Lasers Subject to Variable Polarization-Optical Feedback
Original language description
In this paper, the influence of variable polarization angle of the optical feedback on the relative intensity noise (RIN) of a vertical-cavity surface-emitting laser (VCSEL) is experimentally investigated. VCSEL lases in two orthogonally polarized (XP and YP) modes. For the dominant polarization mode (i.e. XP) the RIN is minimum at a polarization angle of 0o, while it is a minimum at 90o for the suppressed polarization mode (YP) it is minimum at a polarization angle of 90o. Furthermore, for a high optical feedback level the RIN of the XP mode increases rapidly with the polarization angle, whereas for the YP mode the RIN is low for angles > 45°. In addition, result shows that the relaxation oscillations are damped due to the optical feedback. We also show that as the polarization angle of the optical feedback increases a number of spectral lines appear in VCSEL spectrum, thus representing the complex dynamics behavior induced by the feedback.
