A novel class of low-cost and high resolution spectrometer-on-chips has been developed that are suitable for numerous laser-monitoring applications. The technology is based on the integration of digital planar holograms and a full optical circuitry on the same photonic chip. The prototypes are fabricated at a low-cost by nanoimprint lithography and are packed into the size of a USB key. Nano-spectrometers with a resolution down to 0.5 nm and a spectral range up to 229 nm were successfully demonstrated. The original concept of an on-chip spectrometer integrated into commercial image sensors was demonstrated and opens the route to numerous applications. Our miniaturized spectrometers are defining the state-of-the-art for on-chip spectroscopy, as well as in terms of spectral resolution and bandwidth than for their miniaturized size.
