Limiting the Spectral Diffusion of Nano-Scale Light Emitters using the Purcell effect in a Photonic-Confined Environment

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alexey Lyasota, Clément William Tendaï Jarlov

Partial suppression of the spectral diffusion of quantum dot (QD) excitons tuned to resonance of a nano-photonic cavity is reported. The suppression is caused by the Purcell enhancement of the QD-exciton recombination rate, which alters the rate of chargin ...
