Abstract

We report on the observation of periodic modulations in the second-order photon correlation of single-mode vertical-cavity surface-emitting lasers (VCSELs) in steady-state operations. We realized the fast photon correlation measurement of VCSELs by using a streak camera operated in a photon-counting mode. Fast modulation signals were observed in second-order photon correlations at and around the threshold. The calculations using photon rate equations that include a gain medium dynamics shows that the oscillating signals originate from relaxation oscillations.
