Summary form only given. Vertical-cavity surface emitting lasers (VCSEL) are attractive light sources, particularly suited to applications requiring two-dimensional laser arrays. However, if they are employed in polarisation-sensitive applications, methods of controlling the polarisation state of the VCSEL emission are required. Previous work has shown that the etching of deep trenches close to the VCSEL apertures consistently causes the polarisation pinning of the emission in a polarisation parallel to the etch. For the first time, the mechanism of this phenomenon is investigated.
