This paper reviews some of the most important aspects of MOVPE of III–V semiconductors. The paper starts with fundamental aspects of MOVPE in general, and turns to the use of novel precursors and precursor combinations with special emphasis on impr

A vertical-cavity surface-emitting laser device with polarization stable emission at a predefined angle is investigated. The polarization flip probability is reduced from 32% to 2% when compared to circular symmetric devices and the polarization angl

Coupled arrays of vertical-cavity surface-emitting lasers were realized by patterning the reflectivity of the top-distributed Bragg reflector using a phase-matching layer and a metal grid. For improved current injection and better heat dissipation th

The thickness and position of an oxide layer inside a vertical-cavity surface-emitting laser structure have been optimized for minimum optical scattering loss. In the resulting structure, the index guiding provided by the oxide aperture is very small

The linewidth of electrically pumped vertical-cavity surface-emitting lasers optimized for spectroscopic applications in the near-infrared has been examined in detail. Both a high-resolution scanning Fabry-Perot interferometer and a delayed self-homo

We report the first realized polarization converter based on the concept of hybrid supermodes. A polarization conversion of 93% is achieved for a device length of only 0.25 mm. This represents the shortest polarization converter realized on InP so fa
