Abstract
Polarized |S|=0.99±0.01$| S | = 0.99 \pm 0.01$, and unpolarized |S|=0.03±0.01$| S | = 0.03 \pm 0.01$ emission from a single emitter embedded in a single, cylindrically symmetric device design is presented. The polarization stems from a position offset of the single emitter with respect to the cavity center, which breaks the cylindrical symmetry, and a position‐dependent coupling to the frequency degenerate eigenmodes of the resonator structure is shown. The experimental results are interpreted by using numerical simulations and by experimental mapping of the polarization‐resolved far‐field emission patterns. The findings can be generalized to any nanophotonic structure where two orthogonal eigenmodes are not fully spatially overlapping. [ABSTRACT FROM AUTHOR]
