Abstract

A novel, fast simulation tool for transient response is developed to study jitter and noise caused by lateral cavity interactions in VCSEL arrays. The cavity mode profiles, obtained from a paraxial eigenmode analysis, are used to derive fast 1-D rate equations that implement gain confinement, edge clipping, wide angle scattering and diffraction (self-interference) losses. These equations are augmented by lateral coupling terms describing the interactions among nearest neighbor cavities. Slow time scale coupling describes interactions of phase-shifted cavities via mutually induced electric polarization, cross-hole burning and cross-cavity gain due to optical fringe-field interactions. The tool is used to study cavity cross-talk, lateral bit pattern error effects, and the possibility of excitation of long range modulations over the array. Conclusions relating VCSEL packing density to BER, bit suppression by neighboring cavities, and array phase locking are given.
