Pulsed and continuous wave (CW) characteristics of visible vertical-cavity surface-emitting lasers (VCSELs) are presented. A simple thermal model which is used to calculate the temperature profile in a device under CW operation as a result of self-he

The design of visible vertical-cavity surface-emitting lasers (VVCSELs) is improved by using numerical simulations based on the drift-diffusion model which take into account such specific features of the VVCSELs as multiple interfaces and indirect ba

Ultra thin films of single crystal GaAs have been fabricated by selective etching of epitaxial layers grown by Molecular Beam Epitaxy. The resulting membranes are 50nm thick. The results of optical absorption and photoconductivity (PC) measurements a

We describe a vertical-cavity surface-emitting laser (VCSEL) and liquid-crystal modulator (LCM) system. The LCM controls external optical feedback into the VCSEL to produce a single switching element that has an enhanced contrast ratio compared to an

We report electrical control of the polarization state of a vertical-cavity surface-emitting laser (VCSEL), The VCSEL is subject to strong external optical feedback (up to 6% of emission), with polarization controlled by a liquid-crystal (LC) element

We have designed and fabricated a novel VCSEL device which incorporates a cylindrical Bragg waveguide (BW) across the VCSEL. A cylindrical Bragg waveguide is composed of a series of concentric annuli of alternating high and low refractive indices sur

Electron leakage into the p-DBR is the major process limiting the performance of visible VCSELs. It can be reduced by improving electron confinement, or made less important by reducing the mirror reflectivity. By doing this we would then expect to me
