Diffraction from oxide confinement apertures in vertical-cavity lasers

Direct measurement of scattered fields from oxide confinement apertures in vertical-cavity lasers is presented. Diffraction fringes associated with each transverse lasing mode are detected in the far field from devices with varying oxide aperture dimensions and with quantum efficiencies as high as 48%. The diffracted pattern symmetries match the rectangular symmetry of the oxide apertures prese...

Vertical-cavity surface-emitting lasers with lateral carrier confinement

Introduction: Optics is a viable solution to address the limitations of copper-based electronics in short-distance interconnects [1]. In these compact systems, devices must meet the stringent requirements imposed by the power budget and the thermal restriction. Recently, VCSELs have received considerable interest for board and chip level interconnects owing to their small footprints, ease of fa...

Spontaneous emission factor in oxide confined vertical-cavity lasers

We report on measurements of the spontaneous emission factor for oxide-confined InGaAs vertical cavity surface emitting lasers. The spontaneous emission factor is determined as a function of the active layer volume from the measurement of small-signal harmonic distortion at threshold. For a 333 mm oxide aperture device we obtain spontaneous emission factor of 4.2•10 at room temperature. © 1997 ...

Cold-cavity measurement of optical loss from oxide-confined vertical-cavity surface-emitting lasers

Microcavity laser design and performance optimization requires a quantitative knowledge of the cavity optical losses. A generalized method using sub-threshold spectral measurements matched to model calculations is demonstrated to determine optical loss in microcavity lasers. Cold-cavity spectral characteristics are used to extract the size-dependent optical loss for small diameter oxide-confine...

Vertical 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...
