Abstract :
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 of 1 GHz and that reflection noise is significantly reduced with modulation.
