| Amplitude-Squeezed Emission From a Transverse Single-Mode (2007) | |||||||||||||
Abstract | |||||||||||||
| a fact that has been attributed to excess noise, and the study of its relevant mechanisms is currently a field of intensive research. In general, mode partition, anticorrelations, and coupling mechanisms among various modes make major contributions to the noise characteristics when emission into multiple modes is present. The importance of anticorrelation between the main lasing mode and longitudinal side modes for low noise or amplitude-squeezed emission has already been demonstrated in edge emitters. 6--8 Because of their special geometry, VCSELs inherently operate in a single longitudinal mode but can exhibit a rich variety of transverse as well as polarization modes. 9 Studies of multitransverse-mode VCSELs have demonstrated a complex noise and correlation behavior of the transverse modes 10 in which even spatial aspects seem to be of importance. 11 Amplitude-squeezed emission from transverse two-mode or multimode VCSELs has been reported and explained by almost perfect ant | |||||||||||||
