Accurate alignment of quantum dots with photonic components

Caption

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a circular grating (center dot in the inset) emits more light than a dot that is misaligned (off-center dot in the inset).
