Abstract

The study of laser frequency noise is of crucial importance in communication applications. Indeed, the frequency noise of a laser has a direct influence on the lineshape and the linewidth. This topic is particularly interesting for Vertical Cavity Surface Emitting Lasers (VCSELs), which optical properties make them key-devices for optical communications. In this paper, we present the frequency-noise spectrum we obtained with selectively-oxidized VCSELs emitting in the range of 850nm. We have noticed different parts in the spectrum: a 1/fn part in the low-frequency range, independent of the output power, and a white-noise part in the high-frequency range, inversely dependent of the output power. The link with the lineshape of the laser is theoretically performed.
