Photonic Integrated Raman Spectrometer (PIRS)

Physical Sciences Inc. (PSI) and the Georgia Institute of Technology (GT) will develop a Photonic Integrated Raman Spectrometer (PIRS) for low-SWaP spectroscopy applications. PSI and GT will use a silicon nitride photonics platform to develop a dual-stage spectrometer that enables simultaneous high bandwidth and high resolution spectroscopy with direct readout. The overall form factor of the spectrometer will be less than a square centimeter while retaining spectral resolution of better than 0.2 nm. PIRS will feature an integrated pump rejection filter for Raman spectroscopy, and provide an upgrade path to integrated light sources and detectors. PIRS will be fabricated with a scalable process, enabling NASA-fieldable devices in the near-term, while ensuring that costs are manageable.
