Title:
STRAIN TUNING INDIVIDUAL QUANTUM DOT EMISSION FREQUENCIES WITH LOCAL PHASE TRANSITIONS
Document Type and Number:
WIPO Patent Application WO/2020/068180
Kind Code:
A3
Abstract:
A technique is described to deterministically tune the emission frequency of individual semiconductor photon sources, for example quantum dots. A focused laser is directed at a film of material that changes form when heated (for example, a phase change material that undergoes change between crystal and amorphous forms) overlaid on a photonic membrane that includes the photon sources. The laser causes a localized change in form in the film, resulting in a change in emission frequency of a photon source.
