Abstract
We experimentally investigate the coupling of spontaneous emission from monolayer tungsten diselenide to resonant plasmonic nanoantennas at cryogenic temperatures. The low temperature conditions enable preserved chiral polarization states of the spontaneous emission with a valley-selective handedness. By back-focal plane imaging of the scattered spontaneous emission we demonstrate a valley-selective directional emission pattern.
