Design of the WS2-based PCSEL. a Sketch of the cavity configuration and an illustration of the surface-normal emission from the active region. The inset shows a cross-sectional view of the WS2 integration scheme. b 3D FDTD simulated field intensity of the fundamental cavity mode near the cavity core region. In both subfigures, white dashed lines are drawn at the interfaces of each PhC region as a visual guide
