Extended Data Fig. 6: Simulated far-field polarization distribution in the momentum space for different moiré photonic crystal configurations.
From: An adaptive moiré sensor for spectro-polarimetric hyperimaging
Far-field polarization distribution in the momentum space when \(\theta =\) 12° and \(h=400\) nm (top row), \(\theta =\) 12° and \(h=500\) nm (middle row), and \(\theta =\) 10° and \(h=500\) nm (bottom row). The polarization fields of emitting upward and downward are different. The blue ellipse represents left-hand polarization (LCP) states, and the orange ellipse represents right-hand polarization (RCP) states. The winding centres of the LCP and RCP are the polarization singularity C-point. The rotational center of the two PhC slabs are perfectly aligned.
