Y. Satuby et M. Orenstein, Mode-coupling effects on the small-signal modulation of multitransverse-mode vertical-cavity semiconductor lasers, IEEE J Q EL, 35(6), 1999, pp. 944-954
We explored in detail the dynamics of multitransverse-mode vertical-cavity
surface-emitting lasers (VCSEL's), which are important for optical intercon
nection applications, We found that the small-signal modulation response ex
hibits a rich structure including multiresonance peaks as well as response
notches. The detailed theoretical and experimental study enabled us to attr
ibute the various features to the coupling level between the participating
modes. The generality of the predictions was tested and approved for severa
l types of multitransverse-mode VCSEL's and even for a coherent VCSEL array
.
