The authors report the measurement of the relative intensity noise (RIN) of large area vertical cavity surface emitting lasers (VCSELs) in a multimode fibre link. It is found that the RIN of the large area VCSELs under modulation is < −120 dBMz below a frequency ofl GHz and that reflection noise is significantly reduced with modulation.
