Abstract

Blue green vertical cavity surface emitting lasers (VCSELs) have been produced in which the active region comprised molecular beam epitaxy (MBE) grown ZnSe layers containing one or more ZnCdSe quantum wells. As a first step towards the production of a workable VCSEL we have produced optically pumped structures which have allowed us to address a number of issues relating to the design of the devices and the reproducibility of the grown active layers. In this paper we discuss those factors which are specific to II-VI compounds relating to the design, growth and fabrication of optically pumped blue green VCSELs, with the emphasis on overcoming problems in producing practical devices. We have demonstrated that with careful control of the growth conditions we have been able to grow structures in which the predicted and measured spontaneous emission peaks differed by only 1%, leading to the growth of VCSEL structures with less than 3% misalignment in the gain and cavity resonances. © 1998 Chapman & Hall.
