Abstract
This paper shows the possibility of stimulated emission in quantum cascades (QC) embedded in a vertical cavity and proposes a design for the first quantum-cascade vertical-cavity surface-emitting laser (QC VCSEL). In the proposed design, the top VCSEL mirror is a monolithic high-refractive-index contrast grating (MHCG), which serves as both an optical coupler and as the region in which the vertical component of the electrical field is induced, enabling stimulating emission from the quantum cascades. Using a three-dimensional, fully vectorial optical model, a stand-alone MHCG is analysed in terms of its possible use as a QC VCSEL mirror. The distribution of the optical field and threshold gain in VCSELs with QC embedded in MHCG are also simulated.
