We report and analyze the supermode switching with current injection found for coherently-coupled dual-element vertical cavity surface emitting laser arrays. The output power, spectral characteristics, far-field mode profile are measured a range of bias operating conditions. coupling-induced enhanced power from an in-phase or out-of-phase is confirmed when approximately equal currents injected into each array element. observe that coherent switches to increasing injection. be consistent coupled theory 1-dimensional spatial model. calculated modal gain supermodes observed supermodes.

Wavelength-Tunable Vertical Cavity Surface-Emitting Arrays
We report a novel individually addressable, individually wavelength tunable 8 x 6 vertical cavity surface-emitting laser (VCSEL) array. A two-dimensional array of individually wavelength-tunable VCSELs is very attractive for free-space optical interconnect in massively parallel computers [ 1-21. VCSEL’s have large mode spacing due to the very short cavity and are particularly suitable for conti...
متن کاملBeam steering via resonance detuning in coherently coupled vertical cavity laser arrays
Coherently coupled vertical-cavity surface-emitting laser arrays offer unique advantages for nonmechanical beam steering applications. We have applied dynamic coupled mode theory to show that the observed temporal phase shift between vertical-cavity surface-emitting array elements is caused by the detuning of their resonant wavelengths. Hence, a complete theoretical connection between the diffe...
متن کاملVertical cavity surface emitting terahertz laser.
Vertical cavity surface emitting terahertz lasers can be realized in conventional semiconductor microcavities with embedded quantum wells in the strong coupling regime. The cavity is to be pumped optically at half the frequency of the 2p exciton state. Once a threshold population of 2p excitons is achieved, a stimulated terahertz transition populates the lower exciton-polariton branch, and the ...
متن کاملIn-phase antiguided bottom-emitting vertical cavity laser arrays
Introduction: Two-dimensional (2D)-phased vertical cavity surface-emitting laser (VCSEL) arrays offer unique advantages for scaling up single-mode power for high-brightness applications such as fibre laser pumps. They tend, however, to operate in the undesirable out-of-phase mode, which has an on-axis null in the far field [1]. In-phase VCSEL arrays with an on-axis maximum in the far field have...
متن کاملPolarization switching control in vertical-cavity surface-emitting lasers
Orthogonal polarizations within vertical-cavity surface-emitting lasers ~VCSEL! lase at slightly different wavelengths. We describe the use of optical feedback to confine polarization variations to reproducible injection currents. An external cavity is used to select specific wavelengths that reflect back into the VCSEL, hence, changing the cavity Q for the different polarization states. With t...
