Out-of-plane photon emission in 2D semiconductors is rare but crucial for efficient light manipulation in planar optoelectronic devices and photonic chips. Here, an out-of-plane dipolar component of trions in monolayer WSe2 is revealed by exciting the whispering gallery modes of SiO2 microspherical resonators.
