Enhancing semiconductor quantum dot emission with electric and magnetic dipole modes in Mie metasurfaces

Placing a GaAs quantum dot (QD) within a Mie metasurface permits fine tailoring of the dot emission properties. We aligned the electric and magnetic dipole modes with the QD's emission wavelength to enhance the emission in comparison to an unstructured layer. This enhancement is analyzed using numerical simulations of modes supported by the metasurface and the effects QD position and polarization. We will discuss the comparison between the numerical results and experimental photoluminescence measurements.
