Ultra-compact photodetection in atomically thin MoSe$_2$

Autor: Blauth, M., Vest, G., Rosemary, S. Loukkose, Prechtl, M., Hartwig, O., Jürgensen, M., Kaniber, M., Stier, A. V., Finley, J. J.

Excitons in atomically-thin semiconductors interact very strongly with electromagnetic radiation and are necessarily close to a surface. Here, we exploit the deep-subwavelength confinement of surface plasmon polaritons (SPPs) at the edge of a metal-i

Coexistence of weak and strong coupling with a quantum dot in a photonic molecule

Autor: Lichtmannecker, S., Kaniber, M., Echeverri-Arteaga, S., Andrade, I. C., Ruiz-Rivas, J., Reichert, T., Becker, M., Blauth, M., Reithmaier, G., Ardelt, P. L., Bichler, M., Gómez, E. A., Vinck-Posada, H., del Valle, E., Finley, J. J.

We study the emission from a molecular photonic cavity formed by two proximal photonic crystal defect cavities containing a small number (<3) of In(Ga)As quantum dots. Under strong excitation we observe photoluminescence from the bonding and antibond

A few-emitter solid-state multi-exciton laser

Autor: Lichtmannecker, S., Florian, M., Reichert, T., Blauth, M., Bichler, M., Jahnke, F., Finley, J. J., Gies, C., Kaniber, M.

We report a combined experimental and theoretical study of non-conventional lasing from higher multi-exciton states of a few quantum dot-photonic crystal nanocavity. We show that the photon output is fed from saturable quantum emitters rather than a
