Abstract

A vertical cavity surface emitting (SE) laser is promising for laser disks and lightwave communications because of its characteristics of narrow circular beam, single-mode operation and so on. For polarization sensitive applications such as magneto-optic disks and coherent detection, the polarization state of lasers must be well defined. The polarization characteristic of SE laser was found to be linearly polarized in another experiment [1],[2], but detailed characteristics such as its direction have not been studied. In this study, the polarization characteristic of MOCVD grown CBH SE lasers was measured and found to be linear along the crystal direction. Also, we discuss the selectivity of the polarization state.
