Vertical cavity surface emitting laser, optical transmitter-receiver module using the laser, and parallel processing system using the laser
TL;DR: In this article, a vertical cavity surface emitting laser providing mirrors at least one of which has a high reflectivity to be obtained with a small number of pairs each comprising a semiconductor low-refractivity layer and a semiconducting high-reflectivity layer.
Journal ArticleDOI
High-power highly-reliable operation of 0.98-/spl mu/m InGaAs-InGaP strain-compensated single-quantum-well lasers with tensile-strained InGaAsP barriers
TL;DR: In this article, the authors compared 098-/spl mu/m laser with a strain-compensated active layer consisting of a compressive InGaAs well and tensile-strained InGAsP barriers with identical laser that have a conventional active layer with GaAs barriers.

TL;DR: In this article, two multichannel 1.3-μm lens integrated surface-emitting laser arrays for massive data links were fabricated, and the basic structure of the lasers consists of a short InGaAlAs multiple-quantum-well distributedfeedback (DFB) active-stripe array with both a 45° total reflection mirror and an aspheric collimation lens.
Journal ArticleDOI
Characterization of the Refractive Index of Strained GaInNAs Layers by Spectroscopic Ellipsometry
TL;DR: In this paper, the authors characterized the refractive index of strained GaInNAs layers using spectroscopic ellipsometry (SE) and found a large density of states in the conduction band characteristics of this type of material system that includes nitrogen atoms.
