Abstract

An issue of great importance for many of current and potential applications is the transverse-mode behaviour in vertical-cavity surface emitting lasers (VCSELs). Multi­transverse mode operation is essential when VCSELs are used in multimode fiber-based optical interconnection systems. An important consideration for such applications is the understanding of issues like small signal modulation response or Relative Intensity Noise (RIN). In fact recent studies show a rich structure including multiresonance peaks in both small signal modulation response and RIN. An analytical calculation of these quantities taking into account the spatial dependence of the problem could be performed if an analytical solution for the steady state would be available. Another application in which this analytical calculation can be of interest is the design of optoelectronic systems incorporating VCSELs [1]. An effective system design often requires a large number of simulations for design optimization and verification. Then numerical models with low computational cost are essential [1]. Minimum computational cost would be given by the analytical solution.
