Extended Data Fig. 5: Band structure measurement of moiré PhC.
From: An adaptive moiré sensor for spectro-polarimetric hyperimaging
(a) Schematic of the measurement set-up. The red line represents the incident light, its direct transmission, and radiation-induced scattering from the bilayer lattice. POL - Polarizer; QWP - Quarter-Wave Plate; L - Lens; OBJ - Objective Lens. (b) Band structure measured by stacking iso-frequency contours for each wavelength. The dashed line area on the top surface shows the iso-frequency contour, and the cross-section reveals the band structure. (c) Band structure measured by SuperK laser.
