Abstract

Cavity-enhanced nano- and microlasers are of high scientific interest as they offer not only a rich spectrum of exciting physics [1], but also have high potential regarding applications in the field of photonic quantum technologies [2]. Advances in the epitaxial growth and the fabrication of semiconductor micro- and nanolasers paved the way to approach the limit where a few quantum dots (QDs) can drive the device to lasing [3]. However, up until now, QD-microlasers have been exclusively based on standard self-assembled QDs which suffer from their random spatial and spectral position relative to the cavity mode. To further push the field of QD microlasers it is highly desirable to apply deterministic fabrication technologies tailor and maximize their optical gain.
