Towards the transverse mode-locking of oxide-confined VCSELs

We have investigated the lasing modes of oxide-confined vertical-cavity surface emitting lasers (VCSELs). The individual Laguerre–Gaussian modes have been spectrally and spatially resolved with scanning confocal microscope with time resolution of 4ps. Subject to the injection of ultrafast laser puls...

Summary:We have investigated the lasing modes of oxide-confined vertical-cavity surface emitting lasers (VCSELs). The individual Laguerre–Gaussian modes have been spectrally and spatially resolved with scanning confocal microscope with time resolution of 4ps. Subject to the injection of ultrafast laser pulses, the VCSEL showed irregular pulsed emission which indicates the potential for transverse mode-locking of the VCSEL.
