摘要
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 4 ps. 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. (C) 2012 Elsevier B.V.
