Fig. 1. Simulation of the confined modes in the device for a 2.5 µm diameter cavity and a 0.95 µm waveguide. (a) Intensity of the 𝑥
(𝑦) electric field component for the 𝑥(𝑦)
-polarized confined cavity mode. The two modes, split by 0.05 nm and overlapping by 92%, have different strengths but similar spatial extent. (b) Far-field image of the device with the cavity in the center when pumped from the side, as illustrated in (c) and (d). The far field is on a half-sphere calculated at 1 m distance from the device and is plotted in polar coordinates. The intensity does not match the common intensity scale on the right. The intensity of the total scattered light to the top is less than 10−4. (c), (d) Electric field propagating in the waveguide at the height of the quantum dots, injected on the left into the fundamental eigenmodes of the waveguide; (c) is polarized along the 𝑦
and (d) along 𝑧 direction.
