VCSELs (vertical-cavity surface emitting lasers) and VCSEL-based devices

TLDR
In this paper, the cross-sectional dimension of the p-DBR is so limited as to permit only a single fundamental transverse mode in a waveguide composed by the pDBR.
Abstract
In order to control polarization direction of laser light emitted by a vertical cavity surface emitting laser (VCSEL), cross-sectional dimension of the p-DBR is so limited as to permit only a single fundamental transverse mode in a waveguide composed by the p-DBR. Some VCSEL-based devices are developed using arrays of VCSELs in which each VCSEL has a controlled direction of polarization.
