Abstract

This study demonstrates the feasibility to 60 K operation of photonic crystal (PC) nanocavities for self-assembled InGaAs quantum dots (QDs) in single-photon applications. With the proper quality factor and small mode volume, this PC nanocavity exhibits excellent spontaneous emission enhancement and high thermal stability. Measuring the second-order correlation function of single QD emission yields clear photon antibunching with a small timing jitter of ∼1 ns, which is maintained from T=7 to 60 K. These results demonstrate that PC nanocavities with an appropriate quality factor and mode volume are well suitable for developing thermal-stable single-photon sources.
