Paper Abstract

Since VCSEL cavities posses a natural oscillation frequency, 1-D or 2-D periodic VCSEL arrays behave as oscillator lattices coupled through near neighbor interactions. Modulation of an individual VCSEL will excite modulation waves through the lattice. A dispersion relation for the lattice waves is obtained using optical interaction among nearest VCSELs. It is shown that the excited frequency bandwidth is given by the product of the VCSEL natural frequency times the coupling strength; the latter is parameterized by the ratios a/w and b/a, with a the VCSEL active radius, w the cavity mode waist and b the array period. A connection is made between the lattice wave decay constant and the channel cross-talk for VCSEL array-based interconnects / switch fabrics.
