N2 - High-performance compact spectrometers are crucial for numerous consumer applications. In this work we demonstrate an ultracompact spectrometer able to simultaneously perform visible imaging and near-infrared spectroscopy on a single conventional CMOS image sensor. We utilize a novel bio-inspired dispersive element combining disordered scattering nanostructures with ordered resonances. We demonstrate an angular tolerance of 30°, sub-5nm spectral resolution with 200 nm bandwidth, and high throughput, opening up a new way to achieve high-performance sensing and detection.
