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 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 کاملVertical Cavity Surface Emitting Lasers
The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping. Electrical pump has been less successful, but we have identified the proble...
متن کاملModal Properties of Two-Dimensional Antiguided Vertical-Cavity Surface-Emitting Laser Arrays
We present a detailed analysis on 2-D (4 4 square-lattice) antiguided vertical-cavity surface-emitting laser (VCSEL) arrays based on the effective-index model. The calculation shows that the array can operate under 2-D resonant coupling, provided that the resonance condition in both the horizontal and vertical directions is satisfied. Consequently, the resonant-mode edge radiation loss is inver...
