Active demultiplexing of single photons from a solid-state source (Laser Photonics Rev. 11(3)/2017).

Single photons from a solid state source are deterministically routed into different output modes by a fully integrated active optical switch network. Using a state‐of‐the‐art single photon source made of a single quantum dot in a micropillar cavity and an innovative integrated optical demultiplexer, this scheme is capable of creating manifold single photon states. Such states are a crucial resource for photonic quantum information applications including linear optics quantum computation and quantum communications.
