Abstract :
Summary form only given. With modulation bandwidth of 10-15 GHz, vertical-cavity surface-emitting lasers (VCSELs) have become a suitable choice for optical interconnects. However, the presence of higher order modes in the cavity can cause rapid variations of the spectral, spatial and noise characteristics of the laser beam that can affect the gigahertz performance of these devices. Herein we present measurements of the response of VCSELs excited by 0.8-1-ns pulses that show the importance of mode competition and spatial hole burning in the dynamics in VCSELs.
