Research Highlights:
Broadband continuous single-mode tuning of a short-cavity quantum-cascade VECSEL
—Using reflectarray metasurface technology, GaAs-based short-cavity single-mode lasers were realized with continuous tunability over more than 20% fractional bandwidth. This approach does not sacrifice laser performance; power and wall-plug efficiencies are high and high-quality beam patterns were achieved.

Manipulation of quantum dot emission with semiconductor metasurfaces exhibiting magnetic quadrupole resonances
—Quantum Dots (QDs) were integrated into GaAs metasurfaces; spectral and directional control of the spontaneous emission from QDs was demonstrated. This publication was selected as an Editor’s Pick in Optics Express.
