Low-dispersion ultra-high-bandwidth vertical-cavity surface-emitting laser arrays

Abstract

We show a novel design and operation technique for an array of optically coupled vertical cavity surface emitting lasers enabling high-performance optical transmission. Bandwidths up to 37 GHz have been obtained under single-mode operation with narrow spectral width and increased output power while the laser array is biased at low current density. Using dynamic coupled mode theory analysis we determine important design parameters to engineer for greater enhancement of modulation response.
