Telecom wavelength single-photon emission from quasi-resonantly excited InGaSb/AlGaSb quantum dots

This paper demonstrates the first deterministic single-photon emission at the telecom wavelength of 1500 nm from droplet-etched InGaSb/AlGaSb quantum dots by combining antimonide-based materials with advanced excitation techniques to resolve excitonic fine structure and enable high-quality quantum light sources for fiber-optic networks.

Assessing the classicality of photon echo from excitons in lead halide perovskite nanocrystals

This study demonstrates that photon echo signals generated by excitons in lead halide perovskite nanocrystals exhibit classical behavior with Poissonian statistics and minimal noise, as evidenced by a second-order correlation function of unity and a characteristic function consistent with classical states, despite the system's low signal efficiency.
