Paper Abstract

The purpose of this paper is to present a detailed characterization of a dual-wavelength VCSEL - the BiVCSEL. This device consists of two active optical cavities, which share a coupling mirror and can be independently electrically pumped. We present the output powers for the two emitted wavelengths (short - (lambda) S, long - (lambda) L versus the currents in the two cavities (Itop, Ibot). These ((lambda) S, (lambda) L)-(Itop, Ibot) maps identify the different regimes of operation of the BiVCSEL: emission at only one wavelength (either short or long) and dual-wavelength emission, each domain being delimitated by the threshold curves. These curves are passing through a single point, which identify the dual-emission threshold (Ithtop, Ithbot). The apparition of a parasitic lasing mode due to the oxide apertures will be also presented as well as the competition between this mode and the designed lasing modes of the structure.
