Abstract
We have studied the linewidth around threshold of the lasing and nonlasing polarization mode (x and y) in a TEM00 oxide-confined vertical-cavity semic onductor laser (VCSEL). We experimentally demonstrate: (i) that the nonlasi ng mode shows surprising behavior when the lasing mode passes through thres hold, and (ii) that the polarization fluctuations in a VCSEL are limited by the same quantum noise that sets its finite Schawlow-Townes linewidth.
