From: 3D ultra-broadband optically dispersive microregions in lithium niobate
a Schematic of dispersive array embedded in a LiNbO3 window. b Zigzag laser scanning strategy (dashed line) for fabricating the dispersive array (up) and experimental results (down). E indicates the laser polarization. c Optical microscope image of a fabricated dispersive array. d Schematic of spectral imaging using MOD spectrometer with a dispersive array (left), normal RGB image of a color filter (middle), and MOD image captured by our spectrometer (right). e Reconstructed spectra (solid lines) and reference spectra measured by a commercial spectrometer (dashed lines) at points 1, 2, 3 marked in d (right). Scale bars: 100 µm.
