Abstract:High-performance optical spectroscopy integrated into hand-held platforms, especially smartphones, is vital for numerous consumer applications. However, optical spectrometers pose a challenge for miniaturization due to the fundamental limitations of small-and angle-dependent light dispersion. We introduce a new bioinspired light dispersion technology combining disordered scattering nanostructures with ordered Bragg resonances to achieve an ultralarge and angle-independent dispersion. We demonstrate an ultracom… Show more
